#0183;#32;Pyrolysis characteristics of Shenmu bituminous coal and its pyrolysates were investigated in this paper. The results show that Shenmu bituminous coal is a kind of valuable resource. The semicoke, tar and pyrolysis gas are useful material for industrial production. Friedman method was used to describe Shenmu bituminous coal pyrolysis.
Coal: Anthracite, Bituminous, Coke, Pictures, Formation, Uses. CoalForming Environments: A generalized diagram of a swamp, showing how water depth, preservation conditions, plant types, and plant productivity can vary in different parts of the swamp. These variations will yield different types of coal.

Since bituminous coal is the second oldest form of coal that can be obtained from the earth, it is a surprisingly soft material that has a dull yet tarlike appearance. This means that it is easily distinguishable from other coal types because younger forms like lignite have a brown colour and older forms like anthracite are often very dark black and have a noticeably shiny appearance.
Bituminous coal or black coal is a relatively soft coal containing a tarlike substance called bitumen or is of higher quality than lignite and Subbituminous coal, but of poorer quality than is usually the result of high pressure being exerted on lignite. Its coloration can be black or sometimes dark brown; often there are welldefined bands of bright and dull
