Embodiment 1
[0046] The pseudo-boehmite dry rubber powder RPB90 produced by 1 kilogram of Changling Catalyst Factory and the turmeric powder of 30 grams are mixed uniformly. ) in 1.1 liters of aqueous solution, mixed evenly, continued kneading on a twin-screw extruder to form a plastic body, extruded into a trilobal strip of ф1.1 mm, dried at 120°C for 3 hours, and then roasted at 600°C for 3 hours to obtain Boron-containing shaped alumina carrier Z1. The physical and chemical results of the determination of Z1 are shown in Table 1.
Embodiment 2
[0048] The pseudo-boehmite dry rubber powder RPB100 produced by 1 kilogram of Changling Catalyst Factory is mixed with 30 gram of turnip powder, at room temperature this mixture is mixed with boron trioxide 20g, nitric acid 25 milliliters (mass fraction 65%) Mix 1.2 liters of the aqueous solution of the solution evenly, continue kneading on the twin-screw extruder to form a plastic body, and extrude it into a butterfly-shaped strip of ф1.1 mm. After the wet strip is dried at 110°C for 2 hours, it is roasted at 700°C for 3 hours to obtain boron-containing Shaped alumina support Z2. The physical and chemical results of the determination of Z2 are shown in Table 1.
Embodiment 3
[0051] Weigh 150g of the Z1 carrier and place it in the hydration kettle, add 450g of deionized water, seal the hydration kettle and put it in the oven, heat it with a programmed temperature rise, and control the heating rate to 10°C·min -1 , the treatment temperature is 80° C., and the treatment time is 12 hours. After the completion of the hydrothermal treatment, the alumina was filtered, and then dried at 120° C. for 3 hours to obtain a hydrothermally treated alumina carrier.
[0052] Take 100 grams of carrier Z1 after heat treatment in water, and use 220 milliliters containing MoO 3 170 g / L, NiO 30 g / L mixed solution of ammonium molybdate and nickel nitrate was impregnated for 1 hour, filtered, dried at 120°C for 2 hours, and calcined at 410°C for 4 hours to obtain catalyst C1. Calculated by oxide and based on the load on the surface of the unit carrier, the content of molybdenum oxide and nickel oxide in catalyst C1 is measured by X-ray fluorescence spectrometer, and whe...
