METHOD FOR PREPARING A CATALYST USED FOR ONE-CARBON CHEMICAL REACTIONS THROUGH COPRECIPITATION

摘要

A method for preparing a catalyst used for one-carbon chemical reactions through coprecipitation belongs to the technical field of catalysts and comprises the following steps: at 0-150°C, pretreating soluble metal compounds with an alcohol; after the pretreatment, diluting the alcoholic solution of the metal compounds with water; then slowly mixing the solution with a precipitant and feeding the mixture into a precipitation reactor for a coprecipitation reaction at 0-120°C and at a pH value of 7-13; after the coprecipitation reaction, performing ageing, suction filtration, washing, drying, roasting, tableting, pelleting and reduction, to obtain the catalyst with high catalytic performance and used for one-carbon chemical reactions of Fischer-Tropsch synthesis, methanol synthesis, methane reformation and the like. The precipitation catalyst prepared according to the present invention is high in catalytic activity, reaches a high conversion rate, and has stable reaction performance.
