Abstract��
In this paper, SiO2-TiO2-ZrO2 composite carrier was prepared by coprecipitation method and was used as supports for preparing MoP/SiO2-TiO2-ZrO2 catalyst. In a fixed��bed microreactor, with the naphthalene and dodecane solution as model compound, the effects of the four factors of reaction temperature, reaction pressure, liquid hourly space velocity and volume ratio of hydrogen to oil on the dearomatization were investigated by orthogonal test. The optimized process conditions of hydrodearomatization were obtained as: reaction temperature of 360 �棬reaction pressure of 5 MPa, LHSV(liquid hourly space velocity) of 3 h-1 and volume ratio of hydrogen to oil 400��1, the conversion rate of naphthalene was 91.23%. Under this reaction condition, the cetane number of FCC diesel oil can increase more than 15 unites, and the yield reaches 96.28%.
