Organometallic Modeling of the Hydrodesulfurization (HDS) Process: RheniumCarbonyl-promoted C-S Bond Cleavage and Hydrogenation of Thiophenes and Benozothiophenes

摘要

Heterogeneous Catalytic Hydrodesulfurization (HDS) is the commercial process forremoving sulfbr from organosulfur compounds that are present in petroleum-based feedstocks. This process is important for two primary reasons: First, sulfur poisons precious metal-based reforming catalysts thereby making catalytic reforming more difficult and; Second, during the combustion of petroleum fuels poisonous sulfim oxides (SO(subx),x = 2, 3) could be produced which are known precursors to acid rain formation and a threat to the environment.
