【Abstract】 Low pressure sulfur-resisting methanation is a novel process for production of town gas from water gas.The high performance methanation catalyst SM-95-1 have bes invented. It is not necessary to be reduced and sulfurized before use. Therefore a 1 000 hour pilot test has been carried out for the catalysts SM-95-1 under the conditions:H2/CO=2.0,T=3685 ,P=0.80.01 MPa,S.V.=70030 h-1,the content of sulfide is 0.040.25 %.The following results were obtained:CO conversion (single stage) 4555 %,CH4 selectivity 5560 %,lower heat value of product gas 12.513.5 MJ/M3. The results indicate that the stability of the catalyst is excellent.更多还原
