Abstract
The present disclosure provides a lignite char supported nano-cobalt composite catalyst and a preparation method thereof. In the method, lignite is used as a raw material, and a lignite char supported high dispersion nano-cobalt composite catalyst is obtained by a modified impregnation method followed by a high temperature pyrolysis process. The composite catalyst prepared by the present disclosure has a hierarchical pore structure, a high specific surface area, and uniformly dispersing nano-sized cobalts on the lignite char with controllable particle size, so that the obtained catalyst has an excellent catalytic activity for low-temperature COmethanation; moreover, the preparation process is simple and feasible, the raw materials used are cheap and easily available. Therefore, the composite catalyst is very suitable for industrial production and application.
