Abstract:
     Disclosed is a method for removing hydrogen sulfide and carbon dioxide in chemical industrial gas by catalysis.It is suitable for water gas, natural gas, synthetic gas, fuel gas, e.t.c.The catalyst used is lignin sodium or lignin calcium salt as its major composition or waste black liquid from a paper plant. Since the sulfur obtained has white foam and the sulfur further produced has high purity with this method, especially the catalyst being used is non-poison, non-corrosiveness and quite cheap, it is a reasonable way of sulfur removal with good commercial value.
