Many different classifiions of coal are used around the world however, the three main types of coal are anthracite, bituminous and lignite. Anthracite coal is the hardest. It averages 85%95% carbon content and has the highest heating value of the four types of coal. It is not uncommon to find anthracite that produces well in excess of
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
#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.

Highvolatile bituminous coal is classified on the basis of its calorific value on a moist, ashfree basis (ranging from 24 to 33 megajoules per kilogram; 10,500 to 14,000 British thermal units per pound), while mediumvolatile and lowvolatile bituminous coals are classified on the basis of the percentage of fixed carbon present on a dry, ashfree basis (ranging from 69 to 78 percent for mediumvolatile and from
