| description | A methanol cracking catalyst for methanol-gasoline dual-fuel automobiles comprises, by mass percentage, 7.5%-15.5% of NiO (nickel oxide), 2.0%-6.0% of additive, 78.5%-90.5% of complex carrier, wherein the additive can be two of CuO (cupric oxide), ZnO (zinc oxide), K2O (potassium oxide) or CaO(calcium oxide), and the complex carrier comprises, by weight, 30.0%-80.0% of SiO2 and 20.0%-70.0% of Al2O3. Since the complex of SiO2 and Al2O3 is used as a carrier, nitrate aqueous solution of Ni and the additive serves as impregnation solution, nitrate aqueous solution of active components and the additive are impregnated to the complex carrier by the equal-volume method, and finally the finished catalyst is obtained by drying the complex carrier and the calcining the same for 3-5 hours at the temperature ranging from 500 DEG C to 600 DEG C under air or nitrogen gas atmosphere. The methanol cracking catalyst has the advantages of high activity and fine selectivity and stability. |
