Progress of Technology for Hydrogen Production with Water Electrolyzing and Its Application in Coal to Methanol

The article introduces the traditional processes of hydrogen production with water electrolyzing,and the trends of its research ＆ development,and presents the research advance of hydrogen production from wa- ter photolysis with solar energy and from water decomposition with solar energy photochemical catalysis.Em- phatically the article puts forth the application of hydrogen production with water electrolyzing in methanol synthesis process by syngas from coal gasification.The paper also introduces the fundamentals of methanol synthesis with coal gasification supplemented with hydrogen from water electrolyzing,puts forth the process flowscheme of water electrolyzing,and the engineer assumption of it,and recommends the methanol co-production process scheme adopting Shell coal gasification process supplemented with hydrogen from water electrolyzing.The recommended process possesses the advantage that the carbon component in coal can be fully used while the great amount of CO2 from traditional methanol synthesis process can be reduced.Finally,the paper suggests developing the innovation process following in order and advancing step by step so as to realize its commercial application as soon as possible.
