Embodiment 1
[0036] Example 1 illustrates the alumina carrier used in the catalyst provided by the present invention and its preparation method.
[0037] Example 1
[0038] Take by weighing the dry rubber powder (dry basis is 73% that Changling Refinery Catalyst Factory produces, and wherein pseudo-boehmite content is 68%, and gibbsite content is 5 weight %, and surplus is amorphous alumina) 1000 Gram,, 30 gram turmeric powder (the products of Henan Lankao turmeric glue factory), 30g hydroxymethyl cellulose mixes, add the aqueous solution 1200 milliliters that contains boric acid 24g afterwards, extrude into outer diameter 2.5mm on the plunger type extrusion machine, Raschig ring bar with inner diameter of 1.0mm. The wet strip was dried at 120°C for 4 hours and calcined at 960°C for 3 hours to obtain carrier Z1. The physical and chemical properties of carrier Z1 are shown in Table 1.

[0040] carrier number
Embodiment 2
[0043] Get the carrier Z1200 grams that embodiment 1 prepares, use 500 milliliters to contain V 2 o 5 50 g / L, NiO14 g / L mixed solution of ammonium metavanadate and nickel nitrate was impregnated for 1 hour, filtered, dried at 120°C for 4 hours, and calcined at 400°C for 3 hours to obtain protective agent C1. The composition of protective agent C1 is listed in Table 2.
Embodiment 3
[0047] Get the carrier Z1200 grams that embodiment 1 prepares, use 500 milliliters to contain V 2 o 5 18 g / L, NiO 28 g / L mixed solution of ammonium metavanadate and nickel nitrate was impregnated for 1 hour, filtered, dried at 120°C for 4 hours, and calcined at 400°C for 3 hours to obtain protective agent C2. The composition of protectant C2 is listed in Table 2.
