| 摘 要： | 在氢氧化铝干胶挤条成型时,调节纳米炭黑的加入量和水/粉质量比,制备了孔径呈双峰分布、具有较大孔容和比表面积的γ-Al2O3载体。当炭黑加入质量分数为13%、水/粉质量比1.15时,制备的孔径呈双峰分布的γ-Al2O3载体的孔容为0.80mL/g、比表面积为309m2/g,4～10nm和10～15nm孔径分别占总孔容50.8%和35.1%(体积分数),采用该载体制备的NiMoP/γ-Al2O3催化剂的孔径呈明显的双峰分布。在反应温度370℃、氢分压10MPa、氢/油体积比700、体积空速1.5h-1的条件下,制备的NiMoP/γ-Al2O3催化剂可使减压和焦化混合蜡油的硫质量分数由25600μg/g降至2070μg/g,脱硫率为91.9%,而参比催化剂仅可使减压和焦化混合蜡油硫质量分数降至3450μg/g,脱硫率为86.5%。

| Abstract: | The γ-Al2O3 of bimodal porous distribution with larger pore volume and surface area could be obtained through regulating the addition content of nano carbon black and the water/powder ratio in extruding process of pseudo-boehmite. On the conditions of 13% (mass fraction) addition content of carbon black and 1.15 mass ratio of water to pseudo-boehmite in extruding process, The γ-Al2O3 of bimodal porous distribution with BJH average pore diameter of 4-10 nm (50.8%) and 10-15 nm (35.1%), a pore volume of 0.80 mL/g, a BET surface area of 309 m2/g was obtained. At the reaction conditions of θ=370℃, p（H2）=10.0 MPa, LHSV 1.5 h-1and H2/Oil volume ration 700, the NiMoP/ γ-Al2O3 catalyst prepared with the γ-Al2O3 of bimodal porous distribution showed higher activity of hydrodesulfurization than the reference catalyst. The sulfur mass fraction of VGO+CGO feedstock could be reduced from 25600 μg/g to 2070 μg/g with the desulfurization rate of 91.9%, while only to 3450 μg/g and 86.5% over the reference catalyst. |
