The physical and chemical characteristics of a sulfur-tolerant semi-water gas methanation catalyst, developed by the authors are described. The range of reaction temperature is 400-550℃. The pressure is no smaller than 0.6MPa. The sulfur content in the raw gas is in the range of 500-5000ppm(mol). The space velocity is about 1000h-1. The conversion of carbon monooxide is about 40%. The intrinsic kinetics equations are as follows:
