摘　　要：采用混捏方法制备了以ZnO-活性炭为吸附脱硫主要组分的脱硫吸附剂,采用XRD,BET,Py-IR等手段对吸附剂进行表征,并在10mL固定床微型反应器上对吸附剂进行脱硫性能评价。实验结果表明,C3-B吸附剂(活性炭质量分数为30%)具有优异的脱硫性能,且性能稳定。以加氢汽油为原料,在压力1 MPa、空速1.0h-1、氢油体积比100∶1、温度380℃的条件下,C3-B吸附剂的脱硫率为87.1%,产品的硫质量分数为10.0μg/g,达到国Ⅴ排放标准要求。A desulfurization adsorbent ZnO-AC（active carbon）was prepared by kneading method. The sorbent was characterized by XRD,BET and Py-IR and its adsorptive desulfurization performance was evaluated in a 10 mL high pressure fixed bed micro-reactor using Shenghua hydrotreated FCC gaso-line as a feedstock. The results show that the C3-B adsorbent （30% active carbon）has a good desulfu-rization activity and stability. At 380 ℃,1 MPa,LHSV of 1.0 h-1 ,H2？Oil of 100∶1,the sulfur con-tent can be reduced from 78.2 μg？g of the feed to less than 10.0 μg？g of the product with only 0.9 octane number loss. The sulfur removal rate is 87.1%. The quality of the gasoline product meets the reqirements of national standard phase V.
