2022-4-27 Coal is processed in industry to get some useful products such as coke, coal tar and coal gas. It is a tough, porous and black substance. It is an almost pure form of carbon. Coal when processed in industry gives coke, coal tar and coal gas. Coke is used in the manufacture of steel and in extraction of many metals.

2022-1-10 The various useful products obtained by processing the coal by heating in the absence of air are: (1) Coal gas. (2) Coal tar. (3) Coke. The strong heating of coal in the absence of air is called destructive distillation of coal. If coal is heated in the presence of air, then coal burns to produce mainly carbon dioxide gas and no other useful ...

coal, one of the most important primary fossil fuels, a solid carbon-rich material that is usually brown or black and most often occurs in stratified sedimentary deposits. Coal is defined as having more than 50 percent by weight (or 70 percent by volume) carbonaceous matter produced by the compaction and hardening of altered plant remains—namely, peat deposits. Different varieties
