摘要
以大孔、低堆积密度纳米自组装氧化铝为载体,通过共浸剂改性制备负载Mo-Ni双金属活性组分的纳米自组装MoNi-P柴油加氢催化剂。利用BET方法对催化剂的孔结构进行表征。并在固定床微型反应装置上,通过脱硫率的考察,确定最佳反应条件:压力为6.5 MPa,温度为370℃,空速为1.5 h-1,氢油比为700∶1。同时,对5种不同金属配比的Mo-Ni-P催化剂进行40 h的加氢性能评价。实验结果表明,Mo/Ni质量比为5∶1时,加氢效果较好,其平均脱硫、脱氮和芳烃饱和率分别为95.92%、97.84%和73.50%。
Using self-assembled nano alumina with the large aperture and low bulk density as support,the nanoassembly bimetallic Mo-Ni agents are used to prepare the supported Mo-Ni-P diesel hydrogenation catalysts by coimpregnation method. The pore structures of the catalysts are characterized by the BET method. The optimal experimental conditions are obtained by examining the desulfurization rate in the fixed-bed microreactor：6. 5 MPa of the pressure, 370℃ of temperature, 1.5 h-1 of the space velocity and 700 ： 1 of hydrogen to oil. Meanwhile, the 40 hours of hydrogenation performance of the catalysts with different metal proportions are evaluated. The results show that better hydrogenation effect can be achieved when the mass ratio of Mo/Ni is 5： 1. The average desulfurization rate, denitrification rate and dearomatic saturation rate are 95.92% ,97. 84% and 73.50% ,respectively.
