Abstract

A spectrophotometric based, parallel approach to screen heterogeneous catalysts for hydrodesulfurization has been developed. The method utilizes optical changes resulting from the hydrodesulfurization of 1,1′-binaphthothiophene to 1,1′-binaphthyl to determine catalyst activity. Hydrodesulfurization of 1,1′-binaphthothiophene to 1,1′-binaphthyl results in a loss of conjugation in the binaphthyl ring system. This results in a blue shift of more than 60 nm in the UV-vis spectrum. Since only small amounts of the HDS catalyst and 1,1′-binaphthothiophene are required, a large number of catalysts may be screened simultaneously. The synthesis of the 1,1′-binaphthothiophene and conditions for HDS catalyst screening are described.
