Embodiment 1
[0032] Weigh 100 g of pseudo-boehmite, add 2.5 g of sesame powder, and then add 3% nitric acid aqueous solution, knead and extrude, dry at 120°C for 4 hours, and then calcinate at 650°C for 4 hours to prepare a catalyst carrier. Test the water absorption of the carrier according to the conventional method, and then configure the active component impregnation solution according to the water absorption of the carrier according to the equal volume dipping method. First, weigh out 45ml of ammonia, then add 2g of cobalt nitrate and 60g of nickel nitrate in sequence until it dissolves, and finally make the volume constant with ammonia. The carrier was impregnated with an equal volume impregnation method to make the catalyst carrier fully absorb the active component impregnation solution, and then placed for 12 hours, the catalyst was dried at 120°C for 4 hours, and calcined at 500°C for 4 hours to prepare a catalyst sample Cat-1#.
Embodiment 2
[0034] According to the carrier preparation method in Example 1, 100 g of the catalyst carrier was prepared, and then the active component impregnation solution was configured. The preparation method was the same as in Example 1. First, weigh out 50ml of ammonia, then add 5g of cobalt nitrate and 42g of nickel acetate and stir to dissolve, and finally make the volume constant with ammonia. The metal active component impregnation method, drying and calcination conditions were the same as in Example 1, and the catalyst sample Cat-2# was prepared.
Embodiment 3
[0036] According to the carrier preparation method in Example 1, 100 g of the catalyst carrier was prepared, and then the active component impregnation solution was configured. The preparation method was the same as in Example 1. First weigh 50ml of ammonia, then add 8g of cobalt nitrate and 30g of nickel acetate and stir to dissolve, and finally make the volume constant with ammonia. The metal active component impregnation method, drying and calcination conditions were the same as in Example 1, and the catalyst sample Cat-3# was prepared.
