Since the 1860s, ammonia obtained from the destructive distillation of coal was used as a source of nitrogen for fertilizer purposes. Ammonia liquor was recovered by sulfuric gas absorption that was employed after scrubbing coal gas with water. Ammonium sulfate, the resultant from the process, was then used as fertilizer . It is estimated that ...

Generally, the term 'destructive distillation' is used to refer to the processing of certain organic materials along with limited amounts of oxygen and certain reagents, solvents, or catalysts such as phenols and steam. It can also be used to denote the processing of organic material in an environment void of air (pyrolysis in the absence of air).

When coal is heated strongly in the absence of air, a large number of organic and some inorganic compounds are formed. This process is called destructive distillation of coal. Two products of this process are coal tar and coal gas. Coal tar is a thick black liquid that is a byproduct of the destructive distillation of coal. It contains benzene ...

Cannel coal of the Pennsylvanian subperiod from NE Ohio used to produce coal oil. Coal oil is a shale oil obtained from the destructive distillation of cannel coal, mineral wax, or bituminous shale, once used widely for illumination.. Chemically similar to the more refined, petroleumderived kerosene, it consists mainly of several hydrocarbons of the alkane series, with 10 to 16 carbon atoms ...

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.

Distructive distillation of coal is a process of heating a complex substance coal in limited supply of air so that it breaks down into simplier substances. In this process the coal is heated to 1000 degree celcius in absence of air to obtain different useful components such as coke, coal tar and coal gas. Scholr Boy.

Coal gas is a gaseous mixture, mainly composed of methane, hydrogen, and carbon monoxide that are formed by the destructive distillation (it means heating in the absence of air) of bituminous coal and is also used as a fuel. At times, coal steam is added to react with the hot coke, therefore increasing the yield of gas.

Coal Gas Composition. Coal gas, also known as a gaseous mixture, is a fuel made up of hydrogen, methane, and carbon monoxide produced by destructive distillation (continuous heating in the absence of air) of bituminous coal. Coal is mostly made up of carbon, with varying proportions of additional elements such as hydrogen, sulphur, oxygen, and ...
