(Industrial Relations & HR Terms) the main raw material used in the manufacture of a product. Antimicrobial agents are substance of chemical or biological or biochemical origin which inhibits the growth of microorganisms, such as bacteria, viruses, fungus, algae, or other parasites. Definition of green chemistry. Renewable raw materials may be converted by biological means to feedstocks for the chemical industry. Many of the constituents of crude oil are paraffins. A generic process to produce PHA by bacterial fermentation involves fermentation, separation from the growth medium, and purification. Renewable feedstocks are bound to gradually replace sources of fossil origin (oil, gas and coal), both as fuel and as raw materials for the chemical industry. Glucose from cornstarch is the current choice as a substrate, although advances may enable the use of less expensive lignocellulosic materials. A good/ideal feedstock for biorefinery should be nonfood use for the humans/animals and must offer higher product yield with wide market interest. The discussions in prior chapters relating to foam properties and chemistry apply to flexible foams from a fundamental standpoint. Lubricants combine indispensable performance characteristics in transportation and industry with considerable economic value. A carbon product obtained from liquified carbon feedstock and used mainly in the rubber industry. feedstock noun [ C or U ] uk / fid.stk / us / fid.stk / material that is used to produce something in an industrial process: The plants may need massive amounts of feedstock to make relatively small amounts of fuel. Many products derived from crude-oil refining, such as ethylene, propylene and butadiene, are olefinic hydrocarbons derived from refinery cracking processes, and are intended for use in the petrochemical industry as feedstocks for the production of plastics, ammonia, synthetic rubber, glycol and so on. Green chemistry is the design of chemical products and processes that reduce or eliminate the use or generation of hazardous substances. This could be crude oil or any intermediate refining stream. Flexible polyurethane foam is the largest volume application for polyurethanes and the largest category of cellular polymeric materials [1]. The total cost to the consumer is estimated at $ 8.4 billion a year because producing the required corn feedstock increases corn prices. Privacy Policy. Renewable chemistry research has traditionally focused on finding alternatives to petrochemical-based fuels. This efficiency translates into a strong economic advantage, leading to widespread use of conversion processes in refineries today. Thus, the chemistry of the refining process is concerned primarily with the production not only of better products but also of salable materials and is dictated by the type of reactor, the reactor parameters, and the properties of the feedstocks. William Collins Sons & Co. Ltd. 1979, 1986 HarperCollins When the term feedstock is used for the feed to the entire refinery, it typically means non-crude feedstocks such as VGO and blendstocks. DOE Strategic Goals for the Use of Renewable Feedstocks Dramatically reduce, or even end, dependence on foreign oil (a displacement and energy component) Spur the creation of a domestic bioindustry (an enabling and economic component) Integration of chemicals with fuels will simultaneously address both goals. Feedstock is an integral part of the biorefinery system. Coal tar was the feedstock for all kinds of chemicals until it was replaced by oil in the 1940s. Many of her labs projects focus on replacing petroleum as a feedstock. ethylene glycol - via ethylene oxide hydration Agricultural crops can be roughly divided according to the composition of their (main) economic products, such as sugar, starch (grains, tubers), oilseed, protein, or fiber crop and crops for specialty products (pharmaceutics, cosmetics, dyes, fragrance, and flowers). For example, corn is a feedstock for ethanol production and soybean oil is a feedstock for biodiesel. A feedstock is defined as any renewable, biological material that can be used directly as a fuel, or converted to another form of fuel or energy product. Or the interference of secondary and tertiary products with the course of a reaction and, hence, with the formation of primary products may also be cause for concern.

All rights reserved. noun 0 0 Raw material for industrial processing; often, specif., any of various petroleum products used in making petrochemicals and gasoline. Crude oil is rarely used in its raw form but must instead be processed into its various products, generally as a means of forming products with hydrogen content different from that of the original feedstock. This could be crude oil or any intermediate refining stream. Hence, caution is advised when applying the data from model compound studies to the behavior of petroleum, especially the molecularly complex viscous feedstocks. noun 0 0 Any bulk raw material constituting the principal input for an industrial process. Cellulosic biomass [such as straw or wood] has the potential to become a significant feedstock source for [second-generation] biofuels. Mechanism of inhibition of bacterial growth by antibacterial compounds depends on the target bacteria. stock | \ fd-stk \ Definition of feedstock : raw material supplied to a machine or processing plant Examples of feedstock in a Sentence Recent Examples on the Web Fulcrum plans to produce up to 33 million gallons of fuel per year and process up to 530,000 tons per year of prepared feedstock at the 75-acre site in Gary. And even though the use of bond energy data is a method for predicting the reactivity or the stability of specific bonds under designed conditions, the reactivity of a particular bond is also subject to its environment. This is very necessary when the different types of feedstocks crude oil accepted by refineries are considered. the main raw material used in the manufacture of a product, 8 Top CEOs Give Their Predictions for the Wild Year Ahead, Fossil Fuel Companies Say Hydrogen Made From Natural Gas Is a Climate Solution. And in the present context, it is as well that hydrocarbon derivatives decompose at elevated temperatures. See more. Thereby lies the route to many modern products. These boiling ranges are not always precise to the degree and are subject to variation and depend upon the process used for their production. Alkenes, or olefins, are formed by the cracking of hydrocarbons. Reforming processes produce streams that allow the product to be finished as the term applies to product behavior and utility. These have few, if any, parallels in organic chemistry. PHAs occur naturally in a variety of organisms using various renewable waste feedstocks. Definition of feedstock chemical and sources? In 1936, the first catalytic cracking process - the Houdry process - went on stream. The relative reactivity of crude oil constituents can be assessed on the basis of bond energies but the thermal stability of an organic molecule is dependent upon the bond strength of the weakest bond. Refining processes involve the use of various thermal and catalytic processes to higher-molecular- weight constituents to lower-boiling products (Parkash, 2003; Gary et al., 2007; Speight, 2014; Hsu and Robinson, 2017; Speight, 2017). This is very necessary when the different types of crude oil accepted by refineries are considered. This broad range in molecular weights results in boiling points that range from -160C (-288F) to temperatures on the order of nearly 1,100C (2,000F). Polyurethane chemistry is flexible (Polyurethanes science, technology, markets, and trends). ;), butane (CHXCH2CH2CH3), and the butylene isomers (CHXCH2CH=CH2, CH3CH=CHCH3), all of which can be used as feedstocks for petrochemicals production, (ii) lower molecular weight more volatile liquids of which naphtha (a precursor to gasoline) is an example. Chemistry is a difficult subject for students to learn since it involves many abstract concepts, symbols, and unfamiliar specific terms (Gilbert and Treagust 2009; Tsaparlis et al 2010). However, understanding refining chemistry from the behavior of model compounds - even under refining conditions - is not as straightforward as it may appear. Nevertheless, refinery processes can be divided into three major types: The separation and finishing processes may involve distillation or even treatment with a wash solution, either to remove impurities or, in the case of distillation, to produce a material boiling over a narrower range and the chemistry of these processes can be represented by simple equations, even to the disadvantage of over-simplification of the process (Speight, 2014).

Learn more about feedstock Production Process The production process is the type (s) of technology used to convert renewable biomass into renewable fuel. Besides the main harvested product, (Biotransformation of Waste Biomass into High Value Biochemicals). feedstock - any unprocessed material used as a supply for a manufacturing process. As a brief introduction to the subject, in the process of thermal cracking, catalytic cracking or hydrocracking, the high-molecular-weight constituents of the feedstock decomposed to produce (i) gases, such as methane (CH,), ethane (CH3CH3), ethylene (CH,=CH,), propane (CH,CH,CH3), propylene (CH3CH=CH. Remembering that the word paraffin was derived from the Latin parum affinis meaning little affinity or little reactivity, it must have come as a great surprise that hydrocarbon derivatives, paraffins included can undergo a diversity of reactions thereby influencing the chemistry of refining depending upon the source of the crude oil (Smith, 1994; Laszlo, 1995; Yen, 1998). This report presents an overview of the world petrochemical feedstock demand situation for natural gas, natural gas liquids (NGLs), petroleum liquid feedstocks (naphtha and gas oil), and coal. The transition from mineral oil-based lubes to biodegradable lubricants from renewable raw materials is ongoing. Bio-materials may be substituted for petrochemical feedstocks as petroleum prices rise. feedstocks Frequency: Raw material or fuel required for an industrial process. stock. The demand for petroleum and petroleum products has shown a sharp growth in recent years (Parkash, 2003; Gary et al 2007; Speight, 201 la,b, 2014; Hsu and Robinson, 2017; Speight, 2017); this could well be the last century for petroleum refining, as we know it. In winter, gasoline will typically (in cold regions) have butane added to the mix (to facilitate cold starting), thereby changing the boiling range to 0C-220C (320F-425F). Instead, we could rely on the existing natural gas and electricity infrastructure to transport the feedstock for making clean hydrogenelectricity and methaneto smaller local hydrogen generation facilities. WikiMatrix (i) recovery for sale as a chemical feedstock; eurlex-diff-2018-06-20 Feedstock recycling, also known as "chemical recycling," is the process of breaking down collected plastics into monomers and other basic chemical elements ("depolymerization"). The filtered extract of the mash is the feedstock for the fermenter. During the 1950s, as demand for automobile and jet fuel increased, the hydrocracking process developed was applied to petroleum refining. Learn more about production process Fuel The catalytic cracking process was improved in the 1940s with the use of fluidized or moving beds of powdered catalyst to produce high-octane liquids. Conversion processes are, in essence, processes that change the number of carbon atoms per molecule, alter the molecular hydrogen-to-carbon ratio, or change the molecular structure of the material without affecting the number of carbon atoms per molecule. Feedstock means any controlled substance or new substance that undergoes chemical transformation in a process in which it is entirely converted from its original composition and whose emissions are insignificant; Sample 1 Sample 2 Sample 3 Based on 24 documents The first thermal cracking process - the Burton Process - came into use in 1913. With salt and coal, it formed the main feedstock for the chemical industry until about 1914. Feedstock is any hydrocarbon input to a process unit. To generate a mixture of mainly aliphatic alkenes and lower molecular weight alkanes, reactant alkanes are broken apart at high temperatures, generally in the presence of a zeolite catalyst. The fuels are produced by thermal decomposition of a variety of hydrocarbon derivatives, high-molecular-weight paraffins included. That ranges from pumping it into greenhouses to boost vegetable yields to using it as a feedstock for carbon-neutral fuels. Sample 1 They're generally unprocessed materials that are the initial basis of chemical manufacturing, such as fuel or base chemicals. What is biomass as a feedstock? A petrochemical is a substance made from crude oil using chemical . https://www.thefreedictionary.com/feedstock. 2022 LoveToKnow Media. One of the basic areas of knowledge in learning chemistry is chemical structural formulas. The mixture, which is a temperature-dependent feedstock separated by fractional distillation. It is a member of the actinide group . These latter processes (isomerization processes) essentially change the shape of the molecule(s) and are used to improve the quality of the product (Speight, 2014). means Plant feedstock other than Ethane conforming to the specifications set forth in the Feedstock Supply Agreement. PHA versatility allows obtaining a broad range of properties. 2017; Speight, 2017, 2019, 2020). Raw material or fuel required for an industrial process. Also, it must be easily available at the large scale and should have long-time storage capacity. For example, in a crude oil refinery, the highest value products are transportation fuels: (i) gasoline - boiling range: 35C-220C, 95F-425F, (ii) jet fuel - boiling range 175C-290C, 350F-550F, and (iii) diesel fuel, boiling range 175C-370C, 350F-700F. American Heritage Dictionary of the English Language, Fifth Edition. This shows grade level based on the word's complexity. What are renewable feedstocks? The inclusion of reforming processes in this category is purely for descriptive purposes rather than being representative of the chemistry involved. Feedstock definition, raw material for processing or manufacturing industry. The term usually refers to an organic substance. n. Raw material required for an industrial process. Coal tar was the feedstock for all kinds of chemicals until it was replaced by oil in the 1940s. Abstract. A raw material, also known as a feedstock, unprocessed material, or primary commodity, is a basic material that is used to produce goods, finished goods, energy, or intermediate materials that are feedstock for future finished products. industry A feedstock is a raw material used to provide reactants for an industrial reaction. Hence, caution is advised when applying the data from model compound studies to the behavior of crude oil, especially the molecu- larly complex viscous feedstocks. I want to receive exclusive email updates from YourDictionary. Feed stock is what livestock such as cows,. It's basic commons sense at work here. More: In the context of biofuels, a feedstock is any biomass destined for conversion to energy or biofuel. Define Other Feedstock. NGLs include ethane, propane, butanes, and pentanes plus (C5+), also known as natural gasoline. for the petrochemical. When the term feedstock is used for the feed to the entire refinery, it typically means non-crude feedstocks such as VGO and blendstocks. Chemical Feedstock Inventory means that feedstock and intermediate product, including rail cars, tank bottoms and linefill as applicable but less water, sediment and sludge and hydrocarbon in process units and located in interconnecting pipelines owned by Seller 's Affiliate and located at the Refinery or the Chemical Complex. But the Tech May Not Be Very Green, Building a better chemical factoryout of microbes, Scientists Just Laid Out a Game Plan for Building a Clean Hydrogen Economy, Elon Musks $100 Million Carbon Capture Push. and It states that a raw material or feedstock should be renewable rather than depleting whenever technically and economically practicable. Inhibition (iii) middle boiling-range liquids of which kerosene is an example and which is used in diesel fuel. Yes! fermium - Fermium is the name for the element with atomic number 100 and is represented by the symbol Fm. A refinery is a complex network of integrated unit processes for the purpose of producing a variety of products from crude oil (Chapter 4) (Parkash, 2003; Gary et ah, 2007; Speight, 2014; Hsu and Robinson, 2017; Speight, 2017). Good luck! Chemical feedstocks are any raw materials used in the mass production of chemical products. Feedstock Chemistry in the Refinery Introduction Crude oil is rarely used in its raw form but must instead be processed into its various products, generally as a means of forming products with hydrogen content different from that of the original feedstock. Each R&D area is composed of activities which help improve the efficiency and reliability of feedstocks for conversion into . How a Petrochemical is Produced. The trade-off among product types, quantity, and quality influences the choice of one kind of processing option over another. Chemical feedstocks are any raw materials used in the mass production of chemical products. Renewable feedstocks entail the elimination of non-renewable carbon resources such as coal, oil, and natural gas as feedstocks for organic chemistry, otherwise known as de-fossilization. it means that a chemical or mixture of chemicals, fed into a. They need biobased chemical/material manufacturers to demonstrate safety. Crude oil and the viscous feedstocks (such as heavy crude oil, extra-heavy crude oil, tar sand bitumen, and crude oil residua) contain many thousands of different compounds that vary in molecular weight from methane (CH4, molecular weight: 16) to more than 2,000 (Speight, 1994, 2014). From: Recent Advances in Thermo-Chemical Conversion of Biomass, 2015. Smoothly step over to these common grammar mistakes that trip many people up. ethylene - the simplest olefin; used as a chemical feedstock and ripening stimulant polyethylene - polymerized ethylene; LDPE, HDPE, LLDPE; ethanol - via ethylene hydration (chemical reaction adding water) of ethylene; ethylene oxide - via ethylene oxidation. Is a philosophy that applies to all areas of . Feedstock A feedstock is a type of renewable biomass that is converted into a renewable fuel. Worldwide logistics issues are a factor, but more marginal in the supply question when the determining factor is the ability to convert feedstock to product and bolster the supply chain. What is the definition of feedstock? Also Known As: A feedstock may also be called a raw material or unprocessed material. The modern world is both built from . WILL YOU SAIL OR STUMBLE ON THESE GRAMMAR QUESTIONS? Less than one-third of a typical crude oil distills in these ranges and thus the goal of refining chemistry might be stated simply as the methods by which crude oil is converted to these fuels. Feedstock refers to raw materials (input) fed into a process for conversion into something different (output). As feedstock, the term connotes these materials are . However, not all possible refinery chemistry is included, and the chapter focuses on the chemistry of those processes that are applicable to viscous feedstocks such as (i) thermal processes, which involves the chemistry of thermal decomposition or cracking, (ii) catalytic processes, which involves the chemistry of thermal decomposition in the presence of or initiated by a catalyst, and (iii) hydroprocesses, which involves the chemistry of thermal decomposition in the presence of hydrogen or thermal decomposition in the presence of or initiated by a catalyst. impeding the uptake of biobased materials. Fill in the blank: I cant figure out _____ gave me this gift. Not surprisingly, there were more studies completed in the area of physics compared to the other science disciplines because of its long history in science education research and the complex, counterintuitive, and abstract nature of its concepts. It must be appreciated that the stereochemistry of organic compounds is often a major factor in determining reactivity and properties. It is therefore the purpose of this chapter to serve as an introduction to the chemistry involved in these conversion processes so that the subsequent chapters dealing with refining are easier to visualize and understand. Various improvements to the process were introduced into the 1920s. Any bulk raw material constituting the principal input for an industrial process.
