These catalysts were tested in a batch autoclave reactor after presulfiding with the objective of studying the influence of Co/(Co+Mo) ratio on the hydrodesulfurization (HDS) pathways of benzothiophene (BT) and dibenzothiophene (DBT). The results of this study have clearly demonstrated that the Co/Co+Mo ratio has a significant influence on the overall HDS of BT and DBT as well on the direct desulfurization (DDS) pathway, but showed no influence on the hydrogenation pathway. A Co/Co+Mo ratio of 0.4 was found to be optimum for both overall HDS as well as the HDS by DDS pathway.
