Oct 16, 2019· Coal, one of the most important primary fossil fuels, a solid carbonrich material, usually brown or black, that most often occurs in stratified sedimentary deposits, which may later be subjected to high temperatures and pressures during mountain building, resulting in the development of anthracite and even graphite.
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 municipal lighting, and .

A briquette (French: ; also spelled briquet) is a compressed block of coal dust or other combustible biomass material ( charcoal, sawdust, wood chips, peat, or paper) used for fuel and kindling to start a term derives from the French word brique, meaning brick
Hydrogen can be produced from brown coal by gasification. Coal gasification is a welldeveloped technology and core to current Integrated coal Gasifier Combined Cycle (IGCC) developments used for power generation in Japan, US, EU and China.
Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
