coal gas

Chemistry

A fuel gas produced by the destructive distillation of coal. In the late-19th and early-20th centuries coal gas was a major source of energy and was made by heating coal in the absence of air in local gas works. Typically, it contained hydrogen (50%), methane (35%), and carbon monoxide (8%). By-products of the process were coal tar and coke. The use of this type of gas declined with the increasing availability of natural gas, although since the early 1970s interest has developed in using coal in making SNG.

Chemical Engineering

A fuel gas once produced from the heating of coal in the absence of oxygen. Once used extensively in the nineteenth and early part of the twentieth centuries, coal gas typically contained hydrogen, methane, and a significant amount of toxic carbon monoxide. The by-products of the production were coke and coal tar, which is a residue containing benzene, naphthalene, and other organic compounds. The availability of natural gas in the 1970s led to the decline in its use.
