10–4 mol g–1 h–1). The superior DBT and 4,6-DMDBT HDS performances were assigned to the uniform morphology, well-ordered pore channels, and high B/L ratio of the NiMo/ZS-3 catalyst and the suitable dispersion of the MoS2 active phases. HYD was the preferential route for DBT HDS, while ISO was the preferential route for 4,6-DMDBT HDS because of the high B/L ratio of NiMo/ZS-3. Moreover, the DBT and 4,6-DMDBT
成功合成了不同形态的ZSM-5 / SBA-16(ZS)复合材料。该系列载体用于制备用于二苯并噻吩(DBT)和4,6-二甲基二苯并噻吩(4,6-DMDBT)加氢脱硫(HDS)反应的NiMo / ZS。ZS系列支撑和NiMo / ZS被很好地表征,以研究它们的结构-性能关系。NiMo / ZS催化剂(NiMo / ZS-3)具有均匀的形貌和有序的孔道,显示出DBT和4,6-DMDBT HDS的最大k HDS和TOF值。在NiMo / ZS-3上,DBT的k HDS值(13.9×10 –4 mol g –1 h –1)比参考NiMo / ZS-M催化剂(5.5×10 –4)大2倍以上mol g –1 h –1),是NiMo / SBA-16催化剂的三倍(4.4×10 –4 mol g –1 h –1),几乎是NiMo / ZSM-催化剂的四倍5催化剂(3.5×10 –4 mol g –1 h –1)。此外,NiMo
