Explained: What Is Coal Gasification, How Will It Help
AFP Coal gasification is an insitu method wherein oxygen is infused into the seam together with water and ignited at high temperatures, causing coal to partly oxidised into hydrogen, CO, carbon dioxide (CO2), methane (CH4), and hydrogen sulphide (H2S) Exsitu reactors are designed to simulate the gasification process above the ground's surfaceWhat is Underground coal gasification? The process involves pumping oxygen and steam through a small borehole into the coal seam to produce a small and controlled combustion Unlike coalbed methane, therefore, the actual coal is converted from a solid state into gas The hydrogen, methane, carbon monoxide and CO2 are then siphoned off throughCoal Gasification INSIGHTSIAS
