One kind of coke oven gas methanation catalyst and preparation method

The invention provides a coke-oven gas methanation catalyst and a preparation method thereof. The coke-oven gas methanation catalyst is prepared by loading a certain amount of active ingredients Ni on composite oxide TiO2-ZrO2-SiO2 serving as a carrier, and using rare-earth elements RE and metal M as aids. The catalyst has the advantages which cannot be achieved by other methanation catalysts. The catalyst has the characteristics of high low-temperature activity, sulfur resistance capacity, good high temperature resistance performance and the like, and the function of hydrocarbon cracking andgood antioxidation performance and the like and is easy to prepare.
