摘　　要：实验原料油用回炼油与劣质催化柴油体积比2∶1配比,用一种新型的纳米自组装催化剂对其进行精制,设计正交试验,考察在不同温度、空速和压力下对加氢脱硫(HDS)、加氢脱氮(HDN)和加氢脱芳烃(HDAr)的影响,通过实验得出对HDS、HDN、HDAr效果影响最重要的因子。通过BET的表征,证明在该催化剂FA-1204上是均匀多层分散的纳米粒子,它的平均孔径、孔容、比表面积分别为7.7nm、0.26cm3/g、132.7m2/g,从结果来看其性质优于工业催化剂F-2,考察这种催化剂在劣质环境下的活性以及其耐结焦性并与纳米自组装催化剂FA-20-12以及工业催化剂F-2相比较,结果表明FA-1204的脱硫、脱氮和四环、五环芳烃脱除率分别为66%、34%和74%;F-2的脱硫率、脱氮率和四环、五环芳烃脱除率分别为40%、24%和25%,表明FA-1204的抗结焦性能优于工业催化剂F-2,且对于脱芳烃具有一定的深加工能力。Cycle stock and inferior catalytic cracking diesel oil with volume ratio 2∶1 were used as crude oil,which was refined by a new type of nano self-assembly catalyst.Orthogonal test was designed to investigate the influence of temperature, space velocity and pressure on HDS,HDN and HDAr.The most significant influence factor on HDS,HDN and HDAr was obtained.Through the representation of BET,it is concluded that multilayer dispersion of nanoparticles on the surface of the catalyst FA-1204 was uniformwith average pore diameter 7.7 nm,pore volume 0.26 cm3/g,and specific surface area 132.7 m2/g2 respectively.The results proved that the anti coking performance of FA-1204 was better than industrial catalyst F-2.The liveness and resistance ability of carbonization of catalyst FA-1204 in harsh conditions were compared with industrial catalyst F-2 and nano self-assembly catalyst FA-20-12.The results showed that HDS,HDN,HDAr of the catalyst FA-1204 was superior to industial catalyst,the percent conversion of HDS,HDN and HDAr of FA-1204 were 66%,34% and 74% respectively,and the percent conversion of HDS,HDN and HDAr of F-2 were 40%,24% and 25%,respectively.Therefore,the resistance of coking properties of catalyst FA-1204 was superior to catalyst F-2.In addition,catalyst FA-1204 has a processing capacity of HDAr.
