Comprehensive Commentary for Methanol Synthesis Process Technology of Pulverized Coal Gasification with Hydrogen Produced by Water Electrolysis

When the methanol is synthesized by synthetic gas with a molar ratio H2/CO of 2, produced by using the pulverized coal gasification and water electrolysis, the CO can be fully utilized, the CO2 discharging quantity is zero, so injury of CO2 on greenhouse effect produced in atmosphere can be avoided. The feature, industrialized process, operating parameters and main equipment for the pulverized coal pressurized and pure oxygen gasification process were discussed. Developing progress for hydrogen making process by water electrolysis, its process technology and the design of industrialized electrolyzer were introduced; the progressive situation for improvement and study of modern electrolytic technology was described.
