CATALYST FOR PREPARING HYDROCARBONS FROM CARBON DIOXIDE BY ONE-STEP HYDROGENATION AND METHOD FOR PREPARING SAME

摘要

Disclosed are a catalyst for preparing hydrocarbons from carbon dioxide by one-step hydrogenation and a method for preparing same. The catalyst includes nano-metal oxides and hierarchical zeolites, where the mass fraction of the nano-metal oxides in the catalyst is 10%-90%, and the mass fraction of the hierarchical zeolites in the catalyst is 10%-90%. The catalyst has excellent catalytic performance, good reaction stability and high selectivity for desired products, and in the hydrocarbons, C₂⁼-C₄⁼ reach up to 80%, C₅₊ reach up to 80%, and aromatics reach up to 65%.
