[0034] 1. Preparation of catalyst
[0035] The preparation method of catalyst among the present invention is example with the preparation process of catalyst 1-6, and 1-3 is the preparation technology of catalyst 1, and 4-12 is the preparation technology of catalyst 2, is embodied as follows:
Embodiment 1
[0036] Embodiment 1: Catalyst 1-1
[0037] Weigh 2.13g copper nitrate pentahydrate and 3.22g anhydrous palladium chloride, add to a round bottom flask, add 20wt% NH 4The OH solution was completely dissolved, and 15 g of pseudo-boehmite was added, and stirred at room temperature for 2 h. Afterwards, filter with suction, wash with distilled water until neutral, dry at 120°C for 12 hours, roast in a muffle furnace at 450°C for 3 hours, grind and sieve (80-100 mesh), and obtain the active catalyst 1-1 provided by the present invention.
Embodiment 2
[0038] Embodiment 2: Catalyst 1-2
[0039] Weigh 2.13g copper nitrate pentahydrate, 3.22g anhydrous palladium chloride, 15g pseudoboehmite, add to a round bottom flask, add 20mL distilled water to stir the solution to disperse, use 10wt% NaOH solution as precipitant for precipitation, and precipitate to pH About 10, heat up to 80°C for aging for 4h. After cooling down, filter with suction, wash with distilled water until neutral, dry at 120°C for 12 hours, roast in a muffle furnace at 450°C for 3 hours, grind and sieve (80-100 mesh), and then obtain the active catalyst 1-2 provided by the present invention.
