NOVELTY - A highly-sulfur-tolerant syngas-to-methane conversion catalyst comprises 0.5-45 %mass oxide of metal (M) as active component (I), 0.2-25 %mass oxide of metal (M1) as active component (II), and remaining oxide as carrier.    USE - Highly-sulfur-tolerant syngas-to-methane conversion catalyst (claimed).    ADVANTAGE - The highly-sulfur-tolerant syngas-to-methane conversion catalyst has high methanation activity, does not deposit, and can be prepared by a simple method.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) preparation of catalyst, which involves preparing zirconia carrier by coprecipitating 0.5-1.75 mol/L zirconium nitrate solution and 0.5-1.75 mol/L ammonium hydroxide at 20-60 degrees C without stirring, suction-filtering, aging the precipitate for 2-4 hours, washing, and baking in air at 400-600 degrees C for 4-10 hours, preparing alumina carrier by mixing pseudo-boehmite or aluminum hydroxide with 1-10% dilute nitric acid solution, extrusion-molding a precursor, naturally drying for 16-24 hours at room temperature and then at 80-150 degrees C for 10-16 hours, and baking at 400-600 degrees C for 4-10 hours, loading element (M) in the carrier by impregnating soluble compound of element (M) at room temperature for 4-8 hours, drying at 50-80 degrees C for 4-10 hours and at 100-120 degrees C for 8-14 hours, baking at 400-600 degrees C in air atmosphere for 4-10 hours, soaking in soluble compound of metal (M1) for 4-8 hours at room temperature, drying at 50-80 degrees C for 4-10 hours and at 100-120 degrees C for 8-14 hours, baking in air atmosphere at 400-600 degrees C for 4-10 hours, again loading metal (M1) by impregnating at room temperature for 4-8 hours, drying at 50-80 degrees C for 4-10 hours and at 100-120 degrees C for 8-14 hours, and baking in air atmosphere at 400-600 degrees C for 4-10 hours; and    (2) usage method of catalyst, which involves reacting raw material having a hydrogen sulfide content of 500-6000 ppm and feed gas with hydrogen/carbon monoxide molar ratio of 1.5-4, and reacting in the presence catalyst at 1-8 MPa and 300-650 degrees C, and reaction-gas volume space velocity of 2000-12000 hour-1.
