Embodiment 1
[0047] This example illustrates the preparation and composition of the solid acid catalyst of the present invention.
[0048] Catalyst D-1 is used as the carrier, ammonium molybdate tetrahydrate is the molybdenum source, and nickel nitrate hexahydrate is the nickel source. Ni and Mo were loaded by the equal volume impregnation method, and the catalyst was obtained by drying and roasting after impregnation. The drying and roasting conditions were the same as those in Comparative Example 2.
[0049] The catalyst number is A-1. In catalyst A-1, the solid acid is Y-type zeolite, and the metal component accounts for 2wt%, wherein Ni accounts for 0.44wt%, and Mo accounts for 1.56wt%.
Embodiment 2
[0051] This example illustrates the preparation and composition of the solid acid catalyst of the present invention.
[0052] Catalyst D-1 is used as the carrier, ammonium molybdate tetrahydrate is the molybdenum source, and nickel nitrate hexahydrate is the nickel source. Ni and Mo were supported by an equal-volume impregnation method, and the catalyst was obtained by drying and calcining after impregnation. The drying and calcining conditions were the same as in Comparative Example 2.
[0053] The catalyst number is A-2. In catalyst A-2, the solid acid is Y-type zeolite, and the metal component accounts for 2 wt%, of which Ni accounts for 0.5 wt%, and Mo accounts for 1.5 wt%.
Embodiment 3
[0055] This example illustrates the preparation and composition of the solid acid catalyst of the present invention.
[0056] Catalyst D-1 is used as the carrier, ammonium molybdate tetrahydrate is the molybdenum source, and nickel nitrate hexahydrate is the nickel source. Ni and Mo were supported by an equal-volume impregnation method, and the catalyst was obtained by drying and calcining after impregnation. The drying and calcining conditions were the same as in Comparative Example 2.
[0057] The catalyst number is A-3. In catalyst A-3, the solid acid is Y-type zeolite, and the metal component accounts for 2 wt%, of which Ni accounts for 0.57 wt%, and Mo accounts for 1.43 wt%.
