[0034] The dry basis of 40g, 30g, 10g of USY zeolite (purchased from Zibo, Shandong, silicon-alumina ratio of 10), amorphous silica-alumina (purchased from Zibo, Shandong) and pseudo-boehmite (purchased from Zibo, Shandong) were added to the mixer. To homogeneity, then add 3g scallop powder, 5g volume ratio 1:1HNO to the mixture 3 The solution and 40 g of deionized water were ground into a dough suitable for extrusion. It was extruded through a die into a slender cylindrical shape (1.7 mm in diameter), dried at 120°C and then calcined at 550°C for 4 hours, and then cut into carrier particles with the same size for use (1.7×4.0mm).

[0035] The carrier particles are impregnated with a solution containing ammonium tetrathiomolybdate and ammonium tetrathiotungstate at 40°C, and the content of molybdenum sulfide and tungsten sulfide in the dipping solution is 5% and 9% of the dry weight of the carrier, After aging for 8 hours and drying, the carrier particles w

[0042] Beta zeolite (purchased from Zibo, Shandong, with a silicon-to-aluminum ratio of 13), amorphous silica-alumina (purchased from Zibo, Shandong) and pseudo-boehmite (purchased from Zibo, Shandong) were added to the mixer on a dry basis, respectively. To homogeneity, then add 3g scallop powder, 5g volume ratio 1:1HNO to the mixture 3 The solution and 40 g of deionized water were ground into a dough suitable for extrusion. It was extruded through a die into a slender cylindrical shape (1.7 mm in diameter), dried at 120°C and then calcined at 550°C for 4 hours, and then cut into carrier particles with the same size for use (1.7×4.0mm).
