Solution. The nature of the products of the destructive distillation of bituminous coal, in absence of air, depends largely upon the temperature at which the process is carried out. When such coal is heated to 450°500° C. it yields gas and oily vapours consisting chiefly of paraffin hydrocarbons.
Coke is a grey, hard, and porous coalbased fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.

It is a black, viscous liquid composed primarily of a complex mixture of condensedring aromatic hydrocarbons. It may contain phenolic compounds, aromatic nitrogen bases and their alkyl ...
Coal Tar. Richard D. Phillips, in Encyclopedia of Toxicology (Second Edition), 2005 Uses. Coal tar is a viscous liquid mixture of hydrocarbon compounds, derived along with coke, from the destructive distillation of coal in coking ovens. Coal tar itself may be subjected to distillation, a process that separates groups of the components of coal tar from groups of others.
The process of carbonization would last about 3 hours. Superheated steam is injected continuously into the top of a retort filled by coal. At first, in contact with cool coal, the steam condenses to water acting as a cleaning agent. While temperature of coal rises, the destructive distillation starts.

Compare and contrast the use of coal and coke as fuels. Describe the process of destructive distillation and apply it to the process of converting coal to coke in the blacksmith's forge. Explain how blacksmiths shape iron in the forge and the science behind it. Materials. Access to research materials (library books, World Wide Web)
gasifier. (Show more) coal gasification, any process of converting coal into gas for use in illuminating and heating. The first illuminating gas was manufactured from coal in England in the late 18th century by the process of carbonization or destructive distillation, heating coal in the absence of air, leaving a residue of coke as a byproduct.
Destructive distillation is a chemical process of the decomposition of unprocessed material by heating it to a high temperature. It is the processing of organic material in the absence of air or in the presence of limited amounts of oxygen. It is an application of pyrolysis. This process breaks up or 'cracks' large molecules.
This process is known as Destructive distillation. This coalprocessing procedure can be performed in laboratories. This coalprocessing procedure can be performed in laboratories. Coke, ammonia, coal tar and coal gas are the main byproducts of destructive distillation .
We would like to show you a description here but the site won't allow us.
Metallurgical coke is produced by the destructive distillation of coal in coke ovens. Prepared coal is heated in an oxygenfree atmosphere (coked) until most volatile components in the coal are ... Flow diagrams are provided in Figures and 3 to give an overview of the process from coal preparation to byproduct recovery. These ...
The primary objective of coal tar distillation process is to produce a number of tar acid products from the crude tar. The number of fractions, and size of fractions etc., which are to be taken off when tar is distilled is dependent on so many factors. The quality of tar plays a big part.
Destructive distillation is a process of breaking down a substance into its component parts by heating it to a high temperature in the presence of a catalyst. The process is used to produce a variety of substances, including ethanol, methanol and benzene. Destructive Distillation of Coal Diagram. The diagram illustrates the process of ...

Destructive Distillation of Coal helps to obtain several commercially important compounds such as coke, ammonium hydroxide, coal gas, and coal tar ...
Destructive distillation is a process involving the decomposition of a solid by heating it in a closed container and collecting the resultant volatile components and is mainly used for the distillation of coal. Fractional distillation is the process of separating volatile components of miscible liquids on the basis of difference in their ...
Destructive distillation is the process of decomposing a material by heating in a closed container in an inert atmosphere and collecting off the volatile constituents. Destructive distillation of coal produces many byproducts. In the process, heated coal turns into coke, ammonia dissolves in water to form ammonia liquor and coal gas and coal ...
The process of heating coal in the absence of air is called the destructive distallation of coal. Coal contains a number of elements such as carbon, hydrogen, oxygen, nitrogen and sulphur.
