Abstract

The invention belongs to the field of catalysis and environment protection, and more specifically relates to a loaded nano silicon carbide nickel-based catalyst, and a preparation method thereof. According to the preparation method, nano silicon carbide, copper acetylacetonate, 1-hexadecanethiol, nickel ion, ammoniacal liquor, and cerous sulfate are taken as raw materials to prepare the loaded nano silicon carbide nickel-based catalyst. The preparation method is simple; reaction conditions are mild; and large-scale production is convenient to realize. In reaction process, copper acetylacetonate is reacted with 1-hexadecanethiol firstly so as to realize combination of cuprous sulfide and nano silicon carbide, and obtain a nano silicon carbide/cuprous sulfide compound; the surface of the nano silicon carbide/cuprous sulfide compound is loaded with nickel hydroxide via deposition, and then is loaded with a small amount of auxiliary agent cerium. According to the loaded nano silicon carbide nickel-based catalyst, nano silicon carbide is taken as a carrier, nickel and copper are taken as active components, cerium is taken as an auxiliary agent; the loaded nano silicon carbide nickel-based catalyst is used in biomass gasification hydrogen production; catalytic activity and selectivity are high; catalytic reaction conditions are relative mild; production cost is low; and application prospect in industrialized production is promising.
