Embodiment 1
[0045] Weigh 50 grams of commercial MgO, add 500 grams of deionized water, heat and stir in a water bath at 90°C for 2 hours, filter the water in the solution with suction, dry the product at 80°C for 15 hours, and roast at 450°C for 8 hours to obtain the finished catalyst II.
[0046] will load tungsten oxide 10% SiO 2 Calcined at 450°C for 8 hours, mixed with Catalyst II at a ratio of 1:6 (mass ratio), installed in a Φ25mm fixed-bed reactor, using propylene as raw material, at a weight space velocity of 10 hours -1 , the reaction temperature was 300°C, and the reaction pressure was 3MPa to evaluate the performance of the catalyst. The results are shown in Table 1.
Embodiment 2
[0048] Weigh 50 grams of commercial MgO, add 500 grams of deionized water, heat and stir in a water bath at 90°C for 2 hours, filter the water in the solution with suction, dry the product at 80°C for 15 hours, and roast at 450°C for 8 hours to obtain the finished catalyst II.
[0049] will load tungsten oxide 15% SiO 2 Calcined at 450°C for 8 hours, mixed with Catalyst II at a ratio of 1:6 (mass ratio), installed in a Φ25mm fixed-bed reactor, using propylene as raw material, at a weight space velocity of 10 hours -1 , the reaction temperature was 300°C, and the reaction pressure was 3MPa to evaluate the performance of the catalyst. The results are shown in Table 1.
Embodiment 3
[0051] Weigh 50 grams of commercial MgO, add 500 grams of deionized water, heat and stir in a water bath at 90°C for 2 hours, filter the water in the solution with suction, dry the product at 80°C for 15 hours, and roast at 450°C for 8 hours to obtain the finished catalyst II.
[0052] The loaded tungsten oxide 5% SiO 2 Calcined at 450°C for 8 hours, mixed with Catalyst II at a ratio of 1:6 (mass ratio), installed in a Φ25mm fixed-bed reactor, using propylene as raw material, at a weight space velocity of 10 hours -1 , the reaction temperature was 300°C, and the reaction pressure was 3MPa to evaluate the performance of the catalyst. The results are shown in Table 1.
