Coal Gasification Technology an overview ScienceDirect

Coal gasification technology is the conversion of a carbonaceous material by reaction with oxygen and steam to produce synthesis gas (syngas) that is a feedstock to produce more valuable and higher quality liquid fuels such as diesel and kerosene. During gasification there are hundreds of simultaneous reactions taking place. However, the six principle heterogeneous and homogeneous reactions

Coal Gasification Encyclopedia

Coal gasification. The term coal gasification refers to any process by which coal is converted into some gaseous form that can then be burned as a fuel. Coal gasification technology was relatively well known before World War II, but it fell out of favor after the war because of the low cost of oil and natural gas.Beginning in the 1970s, utilities showed renewed interest in coal gasification
