Coal gas | chemical compound | Britannica.com

Coal gas: Coal gas, gaseous mixture—mainly hydrogen, methane, and carbon monoxide—formed by the destructive distillation (i.e., heating in the absence of air) of bituminous coal and used as a fuel. Sometimes steam is added to react with the hot coke, thus increasing the yield of gas. Coal tar and coke

Petroleum and Coal - Purdue University

Sub-bituminous coal contains less carbon and more water, and is therefore a less efficient source of heat. Lignite coal, or brown coal, is a very soft coal that contains up to 70% water by weight. The total energy consumption in the United States for 1990 was 86 x 10 15 kJ. Of this total, 41% came from oil, 24% from natural gas, and 23% from coal.
