摘　　要：为评价自制连续重整催化剂的活性,在微型催化重整实验装置上,在氢油体积比为1 200且H2流量为7.2 L/h的工艺条件下,研究了反应温度、反应压力和液时空速对C≥5液态产物收率、芳烃产率、二甲苯产率及汽油辛烷值的影响。结果表明,在反应温度为490℃、反应压力0.35 MPa、液时空速为1.2 h-1的最佳工艺条件下,汽油的研究法辛烷值可达99.8,芳烃、二甲苯收率分别为80.81%,30.31%。In order to evaluate the activity of the self-made continuous reforming catalyst,the effects of reaction temperature, reaction pressure and liquid hourly space velocity on the yield of liquid state C≥5, aromatic hydrocarbons, xylene and the octane number of gasoline were investigated under the process conditions of hydrogen to oil volume ratio 1 200 and H2 flow rate 7.2 L/h in a miniature catalytic reforming test unit. The results showed that under the optimized conditions of reaction temperature 490℃, reaction pressure 0.35 MPa, liquid hourly space velocity 1.2 h^-1, the research octane number of gasoline was 99.8, and yields of aromatic hydrocarbon and xylene were 80.81% and 30.31% respectively.
