Embodiment 1
[0038] exist figure 1 In the ebullating bed reactor shown, 30.0 g of vanadium pentoxide; 690 mL of mixed solution of isobutanol and benzyl alcohol is added through feed port 1, and the volume ratio of isobutanol / benzyl alcohol is 10:1. Will N 2 It is blown into the reactor from the feed port 2 to keep the reaction liquid and solid particles in a "boiling" tumbling state. Raise the reaction temperature and keep it at 110±2°C, and keep the reaction time for 3 hours; then feed 38.0 g of concentrated phosphoric acid with a concentration of 85% into the reactor from feed port 1, and the phosphorus / vanadium molar ratio is 1.0. Continue to keep the "boiling" reaction for 6 hours, and the reaction is completed and discharged from the reaction material outlet 3. After the reaction solution was cooled to room temperature, it was filtered, and the filter cake was rinsed three times with a small amount of isobutanol, and then the filter cake was placed in an enamel dish and dried natura...
Embodiment 2
[0040] exist figure 1 In the ebullating bed reactor shown, add 30g of vanadium pentoxide, 0.5g of zirconium nitrate as auxiliary agent, 0.95g of nickel nitrate hexahydrate as auxiliary agent; 690mL of isobutanol and benzyl alcohol mixed solution, The volume ratio of benzyl alcohol is 15:1. Will N 2 It is blown into the reactor from the feed port 2 to keep the reaction liquid and solid particles in a "boiling" tumbling state. Raise the reaction temperature and keep it at 100±2°C, and keep the reaction time for 4 hours; then feed 35.5g of concentrated phosphoric acid with a concentration of 100% into the reactor from the feed port 1, and the phosphorus / vanadium molar ratio is 1.1, and continue to maintain " Boiling shape" was reacted for 6 hours, and the reaction was completed and discharged from the reaction material outlet 3. After the reaction solution was cooled to room temperature, it was filtered, and the filter cake was rinsed three times with a small amount of isobuta...
Embodiment 3
[0042] exist figure 1 In the ebullating bed reactor shown, 30.0 g of vanadium pentoxide; 690 mL of mixed solution of isobutanol and benzyl alcohol is added through feed port 1, and the volume ratio of isobutanol / benzyl alcohol is 20:1. Will N 2 It is blown into the reactor from the feed port 2 to keep the reaction liquid and solid particles in a "boiling" tumbling state. Raise the reaction temperature and keep it at 98±2°C, and keep the reaction time for 4 hours; then feed 34.0 g of concentrated phosphoric acid with a concentration of 95% into the reactor from feed port 1, and the phosphorus / vanadium molar ratio is 1.0. Continue to keep the "boiling" reaction for 8 hours, and the reaction is completed and discharged from the reaction material outlet 3. After the reaction solution was cooled to room temperature, it was filtered, and the filter cake was rinsed three times with a small amount of isobutanol, and then the filter cake was placed in an enamel tray and dried natural...
