  • Coal gasification - Wikipedia

    Coal gasification is the process of producing syngas—a mixture consisting primarily of carbon monoxide (CO), hydrogen (H 2), carbon dioxide (CO 2), natural gas (CH 4), and water vapour (H 2 O)—from coal and water, air and/or oxygen.. Historically, coal was gasified to produce coal gas, also known as "town gas".Coal gas is combustible and was used for heating and municipal lighting, before ...

  • Classification of Coal - Engineering ToolBox

    Coal is a readily combustible rock containing more than 50 percent by weight of carbonaceous material formed from compaction and indurations of variously altered plant remains similar to those in peat.. After a considerable amount of time, heat, and burial pressure, it is metamorphosed from peat to lignite.

    Coal is composed of macerals, minerals and water. Fossils and amber may be found in coal. One theory states that about 360 million years ago, some plants evolved the ability to produce lignin, a complex polymer that made their cellulose stems much harder and more woody. Thus, the first treesevolved. But bacteria and fungi did not immediately evolve the ability to decompose lignin, so the wood did not fully decay but became buried under sediment, eventually turning into coal. About 300 million ye

    Coal classification, any of various ways in which coal is grouped. Most classifications are based on the results of chemical analyses and physical tests, but some are more empirical in nature. Coal classifications are important because they provide valuable information to commercial users (e.g., for power generation and coke manufacturing) and to researchers studying the origin of coal.

    Sapropelic coal, hydrogen-rich coal, including cannel coal and boghead coal (see torbanite), derived from sapropels (loose deposits of sedimentary rock rich in hydrocarbons) and characterized by a dull black, sometimes waxy lustre. Sapropelic coals are rich in liptinites (microscopic organic matter derived from waxy or resinous plant parts) and have high yields of volatile matter.
