文摘

A series of novel mesoporous Al2O3 with different crystal forms was synthesized. NiMo/δ-Al2O3 exhibited superior hydrodesulfurization (HDS) activities. Effect of crystal forms on 4,6-dimethyldibenzothiophene (4,6-DMDBT) HDS was found. Hydrogenation (HYD) route was the main pathway in 4,6-DMDBT HDS over NiMo/δ-Al2O3. The HDS reaction network of 4,6-DMDBT over NiMo/δ-Al2O3 was proposed.
