GASIFICATION INDIA 2021. "The government will soon use the around 40% unviable coal mines in the country to make urea through coal gasification which will reduce its production cost by around 50%, Union Minister Nitin Gadkari said. Coal gasification will help reduce the ₹55,000 crore subsidy provided by the government on urea every year".

Insitu gasification of coal or Underground Coal Gasification (UCG) is the technique of converting coal into gas while it is still in the seam and then extracting it through wells. It produces Syngas which is a mixture consisting primarily of methane (CH4), carbon monoxide (CO), hydrogen (H2), carbon dioxide (CO2) and water vapour (H 2 O).

Abstract. Underground coal gasification (UCG) converts coal insitu into a gaseous product, commonly known as synthesis gas or syngas through the same chemical reactions that occur in surface gasifiers. Gasification converts hydrocarbons into a synthesis gas (syngas) at elevated pressures and temperatures and can be used to create many products ...

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 ...
