Examples
Embodiment 1
[0019] Take by weighing 70 grams of pseudo-boehmite dry glue (containing 73wt% of alumina) and 50 grams of kaolin respectively, add 1.41 grams of carbon black, 1.41 grams of asparagus powder, mix uniformly, then add 9.78 grams of ammonia water, add 70 grams of distilled water, Carrier A was obtained by kneading and extrusion, drying at 120°C for 2 hours, and calcining at 800°C for 3 hours.
[0020] Weigh 82.11 grams of ammonium heptamolybdate, add 900 ml of ammonia water with a concentration of 12%, then add 27.94 grams of basic nickel carbonate and stir until completely dissolved, adjust the volume of the solution to 1000 ml with ammonia water to obtain solution L-1. Carrier A was saturated and impregnated with solution L-1, dried at 110°C for 2 hours, and calcined at 500°C for 5 hours to obtain catalyst T-A.
Embodiment 2
[0022] The method is the same as in Example 1, except that 1.94 g of basic magnesium carbonate is added, dried at 120° C. for 2 hours, and calcined at 600° C. for 2 hours to obtain carrier B. Carrier B was saturated and impregnated with solution L-1, dried at 120°C for 2 hours, and calcined at 480°C for 3 hours to obtain catalyst T-B.
Embodiment 3
[0024] Take by weighing 40 grams of pseudo-boehmite dry glue (containing alumina 73wt%) and 70 grams of montmorillonite respectively, add 2.52 grams of carbon black, 2.52 grams of turnip powder and 3.52 grams of ammonium carbonate, mix well, then add 65 grams of Distilled water, kneaded and extruded to shape, then dried at 100°C for 3 hours, and calcined at 600°C for 1 hour to obtain carrier C.
[0025] Weigh 53.30 g of ammonium heptamolybdate, add 900 ml of 12% ammonia water, then add 18.14 g of basic nickel carbonate and stir until completely dissolved, adjust the volume of the solution to 1000 ml with ammonia water to obtain solution L-2. Saturated carrier C was impregnated with L-2 solution, dried at 100°C for 6h, and calcined at 520°C for 3h to obtain catalyst T-C.
