Embodiment 1
[0052] (1) Catalyst preparation
[0053] Weigh 600g of ammonium phosphate, dissolve it in 2000mL of deionized water to obtain solution A; grind 1000g of sulfur-containing petroleum coke to powder, then add it to solution A, leave it for 1.5h, and then filter, and put the obtained solid sample in an oven at 110 Dry at ℃ for 5h. At 200°C, pretreat the dried solid sample with water vapor for 3 hours (the volumetric space velocity of the water vapor gas is 1200 hours -1 ), then raise the temperature to 400°C, continue pretreatment for 3h, and then cool to 60°C under nitrogen protection to obtain pretreated petroleum coke.
[0054] Mix 1000g of the pretreated petroleum coke obtained above and 60g of calcium carbonate uniformly, place in a microwave heating furnace with a microwave frequency of 2450MHz, and treat at 650°C for 2h under a nitrogen atmosphere under the condition of a microwave power of 0.3kw. After cooling, grind the above sample into powder, mix it with a hydrochlor...
Embodiment 2
[0060] (1) Catalyst preparation
[0061] Weigh 500g of diammonium hydrogen phosphate, dissolve it in 2000mL of deionized water to obtain solution A; grind 1000g of sulfur-containing petroleum coke into powder, then add it to solution A, let it stand for 1.5h, then filter, and put the obtained solid sample in an oven Dry at 110°C for 5h. At 200°C, pretreat the dried solid sample with water vapor for 3 hours (the volumetric space velocity of the water vapor gas is 1000 hours -1 ), then raise the temperature to 400°C, continue pretreatment for 3h, and then cool to 60°C under nitrogen protection to obtain pretreated petroleum coke.
[0062] 1000g of the pretreated petroleum coke obtained above and 70g of calcium carbonate were mixed evenly, placed in a microwave heating furnace with a microwave frequency of 2450MHz, and treated under a nitrogen atmosphere at 650°C for 2h under the condition of a microwave power of 0.3kw. After cooling, grind the above sample into powder, mix it ...
Embodiment 3
[0068] (1) Catalyst preparation
[0069] Weigh 400g of ammonium dihydrogen phosphate, dissolve it in 2000mL of deionized water to obtain solution A; grind 1000g of sulfur-containing petroleum coke into powder, then add it to solution A, let it stand for 1.5h, then filter, and put the obtained solid sample in an oven Dry at 110°C for 5h. At 200°C, pretreat the dried solid sample with water vapor for 3 hours (the volumetric space velocity of the water vapor gas is 800 hours -1 ), then raise the temperature to 400°C, continue pretreatment for 3h, and then cool to 60°C under nitrogen protection to obtain pretreated petroleum coke.
[0070] 1000g of the pretreated petroleum coke obtained above and 80g of calcium carbonate were uniformly mixed, placed in a microwave heating furnace with a microwave frequency of 2450MHz, and treated at 650°C for 2h under a nitrogen atmosphere under the condition of a microwave power of 0.3kw. After cooling, grind the above sample into powder, mix i...
