以偏钛酸形式将TiO_2引入到AlPO_4-5/Al_2O_3复合载体中,以W-Ni为活性金属制备了不同TiO_2含量的复合载体催化剂。分别以二苯并噻吩、四氢萘为模型化合物,在微反装置上对催化剂加氢脱硫与芳烃加氢饱和性能进行评价。结果表明,在反应压力4.0 MPa、氢油体积比500:1的条件下,TiO_2质量分数为15.0%时,所制备催化剂的加氢脱硫活性和转化四氢萘的活性均最高。 TiO 2 was introduced into AlPO 4 -5 / Al 2 O 3 composite support in the form of metatitanic acid, and composite catalysts with different TiO 2 content were prepared by using W-Ni as the active metal. Dibenzothiophene and tetrahydronaphthalene were used as model compounds respectively to evaluate the performance of hydrodesulfurization and aromatics hydrogenation in a micro-reactor. The results showed that the hydrodesulfurization activity and the conversion of tetralin were the highest when the reaction temperature was 4.0 MPa and the volume ratio of hydrogen to oil was 500: 1.
