Examples
Embodiment 1
[0031] (1) Put 45g of kaolin into 250g, 4wt% phosphoric acid and soak for 12h, take it out and dry it at 100℃ for 5h to obtain a modified binder;
[0032] (2) Add 486g, 30wt% hydrochloric acid to 1223g, 10wt% pseudo-boehmite suspension and mix to obtain a gel, and add 7.6g, 10wt% heavy magnesium oxide suspension to the above gel Mixing to obtain a mixed solution, the added heavy magnesium oxide contains 80wt% of magnesium oxide;
[0033] (3) Add 52g of cerium nitrate, 8g of ammonium metavanadate and 89g, 33wt% of oxalic acid solution to the above-mentioned mixed solution in sequence and then mix to obtain a mixture;
[0034] (4) Add 44 g of the modified binder prepared in step (1) to the above mixture and mix uniformly to obtain a slurry. The slurry is dried at 400°C for 5 hours and then calcined at 600°C for 5 hours to obtain high activity and high Abrasion resistant sulfur transfer agent 1.
Embodiment 2
[0036] (1) Put 50g of Yanggan clay into 100g, 10wt% ammonium phosphate and soak for 14h, take it out and dry at 150℃ for 4h to obtain modified binder;
[0037] (2) Add 700g, 36wt% of nitric acid to 1067g, 12wt% of pseudo-boehmite suspension and mix to obtain a gel, and add 6.8g, 12wt% of heavy magnesium oxide suspension to the above gel Mixing to obtain a mixed solution, the added heavy magnesium oxide contains 90wt% of magnesium oxide;
[0038] (3) Add 58g of cerium sulfate, 54g of ammonium polyvanadate and 197g of 35wt% citric acid solution to the above-mentioned mixed solution in sequence and then mix them to obtain a mixture;
[0039] (4) Add 47 g of the modified binder prepared in step (1) to the above mixture and mix uniformly to obtain a slurry. The slurry is dried at 500°C for 4 hours and then calcined at 700°C for 4 hours to obtain high activity and high Abrasion resistant sulfur transfer agent 2.
Embodiment 3
[0041] (1) Put 47g of bentonite into 125g, 8wt% ammonium hydrogen phosphate soaked for 13h, take it out and dry it at 120℃ for 5h to obtain a modified binder;
[0042] (2) Add 750g, 32wt% of glacial acetic acid to 1138g, 11wt% of pseudo-boehmite suspension and mix to obtain a gel, and add 7.2g, 11wt% of heavy magnesium oxide to the above gel for suspension The liquid is mixed to obtain a mixed liquid, and the added heavy magnesium oxide contains 85% by weight of magnesium oxide;
[0043] (3) Add 32g of cerium chloride, 47g of ammonium polyvanadate and 193g of 34wt% citric acid solution to the above-mentioned mixed solution in sequence, and then mix them to obtain a mixture;
[0044] (4) Add 45g of the modified binder prepared in step (1) to the above mixture and mix uniformly to obtain a slurry. The slurry is dried at 450°C for 4 hours and then calcined at 650°C for 4 hours to obtain high activity and high Abrasion resistant sulfur transfer agent 3.
