Method for improving catalytic hydrogen production performance of copper-based catalyst

The invention relates to an acid activated montmorillonite supported copper-based catalyst, which takes acid activated montmorillonite as a carrier, an active component is metal copper, and metal additives are Ni, Co, Ce, Zr, La, Fe and V. The specific surface area of the acid activated montmorillonite is 356.93 m < 2 >/g, the pore volume is 0.56 cm < 3 >/g, the pore diameter is 6.24 mm, the loading capacity of the metal copper is 5-10%, the loading capacity of the metal additive is 3-10%, the specific surface area of the Cu-loaded montmorillonite-based catalyst is 214.19-334.06 m < 2 >/g, the pore volume is 0.35-0.52 cm < 3 >/g, and the pore diameter distribution is 5.94-6.58 mm. According to the invention, after montmorillonite is subjected to acid activation treatment, copper and other metal additives are loaded by using an excessive impregnation method, and after the metal additives are added, compared with a catalyst independently loaded with metal copper, the reaction performance of the catalyst is obvi
