摘要

The petroleum used nowadays is increasingly contaminated with sulfur, which upon combustion of fuels produces sulfur oxides (1). The current generation of hydrodesulfurization catalysts are sulfides of Co(Ni)-Mo supported on alumina, and although they are very active for conventional oil, they exhibit low activity towards highly refractory sulfur compounds (2). In the last decades, efforts have been made to develop novel catalysts that can fulfill the new environmental regulations, and the transition metals carbides and nitrides have been identified as potential catalysts for such applications (3). In this regard, the Mo based solids have been receiving most of the attention (3, 4). It is believed that the carbide particles may simply serve as a template on which a strained or highly dispersed, sulfided phase is formed. It has been suggested that during hydrotreating process, these catalysts form a new active site (MoSxCy), which can enhance the HDS activity (5, 6). In the present work we have studied the effect of the carbiding method [conventional (CM) vs. carbothermal (CTH) methods] and operation conditions on the thiophene (TH) hydrodesulfurization (HDS) activity of activated carbon supported Mo catalysts.
