摘要: 以偏钛酸形式将TiO2引入到AlPO4-5/Al2O3复合载体中,以W-Ni为活性金属制备了不同TiO2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4.0MPa、氢油体积比500:1、体积速度7.53 mL/h的条件下,TiO2质量分数为15.0%时,所制备催化剂的加氢脱硫活性最高;在反应压力4.0MPa、氢油体积比500:1、体积速度3.62 mL/h的条件下,TiO2质量分数为15.0%时,催化剂转化四氢萘的活性最高。

Abstract: TiO2 was incorporated into AlPO4-5/Al2O3 support by adding meta-titanic acid. A series of catalysts was prepared using W-Ni active component and Ti-AlPO4-5/Al2O3 composite supports with various TiO2 contents. The catalytic performance (HDS and aromatics saturation) of these catalyst samples were evaluated on a micro-reactor and using dibenzothiophene and tetralin as model compounds respectively. Results showed that as comparing the effect of TiO2 contents, under a reaction pressure of 4.0 MPa, a H2/oil volume ratio of 500 and a certain reaction temperature, the catalyst having a TiO2 content of 15.0% exhibited the best HDS activity and the highest conversion of tetralin.
