Generation Of Methanol From High Ash Coal And Utilization Of Methanol For Syngas Cleaning
Abstract: The present invention discloses and claims a gasification process for the conversion of the high ash coal to syngas and production of methanol from syngas, said process comprises of steps allowing reaction between high ash coal with gasification agent in a fluidized bed reactor; maintaining the operating temperature at 1000oC by feeding enough oxygen; removing continuously the ash formed in initial step; separating and recycling back the fine particles in the syngas to the reactor to improve the carbon conversion; passing said syngas to the water scrubber to remove ammonia & alkali metals and methanol solvent-based absorption column to remove H2S and to reduce CO2 vol % in syngas. Water shift gas reactor is envisaged to adjust H2/ CO ratio. Conditioned syngas is admitted into methanol loop to generate methanol. Part of methanol generated from process will be utilized for removing H2S and CO2 in single absorption column.
