About Coal gasification. It is a process in which coal is partially oxidised with air, oxygen, steam or carbon dioxide to form a fuel gas. This gas is then used instead of piped natural gas, methane and others for deriving energy. India has a reserve of 307 Billion tonnes of thermal coal and about 80% of coal produced is used in thermal power ...

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 ...
