In 1991 Dr. Stompel left the Institute and has established a private company Coal-Chem Engineers & Consultants. As a consultant he participated in several international projects aimed at improving efficiency of coal tar industry in Poland and abroad.
Coal Tar. Coal tar is a thick black liquid which is a by-product of the production of coal gas and coke. It contains benzene, naphthalene, phenols, aniline, and many other organic chemicals. Coal tar is used for medical and industrial purposes. However, coal is also known as cutar, balnetar, liquor carbonis detergens, liquor picis carbonis, etc.
Product Stewardship Summary Coal Tar Pitch (CAS number 65996-93-2) (EC number 266-028-2) Product Description Coal tar pitch is a black, viscous residue that remains after the distillation of coal tar. This process occurs at our plants and involves heating coal tar (the raw material used to produce coal tar pitch) in a still. As the
Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It has both medical and industrial uses. It may be applied to the affected area to treat psoriasis and seborrheic dermatitis (dandruff). It may be used in combination with ultraviolet light therapy. Industrially it is a railway tie preservative and used in the surfacing of roads.
Coal tar sealant is a thick, black goop applied to driveways, asphalt parking lots and playgrounds, primarily in the eastern United States. The sealcoat contains high levels of toxic chemicals that can cause cancer and environmental harm.
Coal tars and coal-tar pitches have many uses in industry and in con-sumer products. Coal tars are used primarily for the production of refined chemicals and coal-tar products, such as creosote, coal-tar pitch, and crude naphthalene and anthracene oils from the distillation of crude coal tar. Coal tar has been used as a fuel in open-hearth fur-
Coal tar is a black, viscous, thick liquid from which a great number of chemical compounds are derived. The first fraction is obtained in the distillation of coal tar contains many aromatics, among them benzene, toluene and xylem. Benzene is the lightest fraction obtained from the distillation of coal tar hydrocarbons.
Coal-tar creosote, also referred to as creosote by the EPA, is formed by fractional distillation of crude coal tars.This compound is used as a wood preservative that acts as a fungicide and pesticide applied in a pressure treatment process, which involves pressurized treating cylinders that force pesticide penetration into the wood.
Dec 26, 2018· Anthracene, Cresol, Crude tar, Dehydration, HBTA, Hydrocarbons, Phenol, tar, tar distillation, Coal Tar and its Distillation Processes. Coal tar, also known as crude tar, is the by-product generated during the high temperature carbonizing of coking coal for the production of the metallurgical coke in the by-product coke ovens.
May 08, 2014· In addition, the carbon anodes contain 13 to 16 wt% coal tar pitch to be used as a binder material, thus binding the coke and butts particles together in the anode.2 The pitch is distilled from the coal tar produced when coke for the iron and steel industry is made from coking of bituminous coal. Coal tar pitch is a complex hydrocarbon mixture ...

A process is disclosed for manufacturing needle coke, which process involves the steps of comminuting a coal, dispersing it in a suitable solvent, subjecting the dispersion to hydrogenolysis liquefaction at 360°-480° C and 1-150 Kg/Cm 2 H 2 pressure, distilling the resultant ashless coal solution at 250°-600° C to remove impurities, and unreacted coal, and coking selected distillate ...
The primary purpose of modern coke ovens is the production of quality coke for the iron and steel industry. The recovery of coal chemicals is an economical necessity, as they equal approximately 35 percent of the value of the coal. To produce quality metallurgical coke, a high-temperature carbonization process is used.
Pitch products are produced by Rain Carbon Inc. from coal tar pitch (CTP), a derivative of coal tar distillation, as well as from specialty petroleum feedstocks. CTP is mainly used as a binder for the production of carbon anodes essential for aluminum smelting.
Production Process Graphite electrode is a kind of high temperature resistant graphite conductive material made of petroleum coke, needle coke, pitch coke, coal tar pitch,etc. The main production process are extrusion forming, baking, impregnation, secondary baking, graphitization etc.
ARTICLES / Coal Tar Epoxy Manufacturing Process | Composition. Coal tar epoxy is made by the conversion of polyamide epoxy with a pitch of refined coal tar. It is mostly used on metal substrates and concrete in offshore, petroleum and industrial environments. The fluctuation of temperatures can make the product crystallize.
Two component and coal tar based polyurethane waterproof membrane includes some ingredients and some materials that are castor oil and polyol using for resin of polyurethane, dehumidifying agent, wetting agent,anti agen using to stop in the mixture during production process, bentonite using as anti collapse agent and etc. In addition to, Coal tar Polyurethane Waterproof Membrane has ...
Occupational exposures during coal-tar distillation were considered by a previous Working Group in 2005 (IARC, 2010). Since that time new data have become available, which have been incorporated in this Monograph, and taken into consideration in the present evaluation.
Tar is a dark brown or black viscous liquid of hydrocarbons and free carbon, obtained from a wide variety of organic materials through destructive distillation. Tar can be produced from coal, wood, petroleum, or peat. Production and trade in pine-derived tar was a major contributor in the economies of Northern Europe and Colonial America. Its ...
How is Crude Coal Tar Derived? INTRODUCTION Crude Coal Tar is a by product of the Coking process. Coking is the process of heating coal in coke ovens to drive volatile matter from it. Metallurgical Coke is used as a fuel and reducing agent in the production of iron, steel, ferro-alloys, elemental phosphorus,
Coal tar is derived from coal. It is a byproduct of the production of coke, a solid fuel that contains mostly carbon, and coal gas. Coal tar is used primarily for the production of refined chemicals and coal-tar products, such as creosote and coal-tar pitch. Certain preparations of coal tar have ...
Coal Tar Distillation Products - Pitch is derived from the process of coal Tar at high temperature using the latest technology under strict process and quality control. The salient features are - (a) Low Volatile content (b) High fixed carbon (c) Low ash content (d) No mesophase (e) Good wettability
