Embodiment 1
[0047] This embodiment provides a catalyst for hydrogenation of organic sulfur, the preparation method of which is as follows:
[0048] Will Al 2 o 3 Powder 60g, TiO 2 Powder 20g, ferrous sulfate 11.89g (4.4g as iron) and diammonium molybdate 6.7g (3.3g as molybdenum) mixed for 15min to obtain the mixture;
[0049] Mix 15g of silica sol with the above mixture for 30 minutes; then send it into an extruder for extruding and molding to obtain a molded product;
[0050] The shaped product was dried at 110°C for 2 hours, and then calcined at 400°C for 2.5 hours to obtain the organosulfur hydrogenation catalyst.
Embodiment 2
[0052] This embodiment provides a catalyst for hydrogenation of organic sulfur, the preparation method of which is as follows:
[0053] Will Al 2 o 3 Powder 70g, TiO 2 18g of powder, 1.71g of iron oxide (1.2g as iron), 4.03g of molybdenum trioxide (2.7g as molybdenum), and 20g of diammonium molybdate (3.3g as molybdenum) were mixed for 15 minutes to obtain a mixture;
[0054] Mix 10g of aluminum sol with the above mixture for 30 minutes; then send it to the extruder for extruding and molding to obtain a molded product;
[0055] After drying the molded product at 100°C for 3 hours, it was calcined at 200°C for 5 hours to obtain the organosulfur hydrogenation catalyst.
Embodiment 3
[0057] This embodiment provides a catalyst for hydrogenation of organic sulfur, the preparation method of which is as follows:
