Abstract

A realistic planar model of a silica-supported NiMo sulfide hydrotreating catalyst was used to study the intrinsic kinetics of thiophene hydrodesulfurization over a broad temp. range at atm. pressure. The specific non-porous nature of the model catalysts excludes possible diffusion limitations, which are commonly encountered in kinetic studies of their industrial porous analogs. The unique possibility to measure the intrinsic chem. kinetics over a large temp. range allowed us to observe a Volcano-type behavior for thiophene hydrodesulfurization. Furthermore, we derived intrinsic kinetic parameters, including the activation energy and adsorption consts. for thiophene and hydrogen sulfide, for this well-characterized NiMo sulfide model catalyst.
