[ESCA and EPR measurements on hydrodesulfurization catalysts after high pressure catalytic reaction]

Primary tabs

Gajardo, P. Mathieux, A. Grange, Paul [UCL] Delmon, Bernard [UCL]

Describes an experimental procedure which allows the study of catalysts after high pressure catalytic reaction without contact with air. Two samples, namely Co/ gamma -Al/sub 2/O/sub 3/ and CoMo/ gamma -Al/sub 2/O/sub 3/, have been studied after hydrodesulphurization reaction at 30 kg.cm/sup -2/ by ESCA and EPR. The results indicate that, depending on the catalyst used, different distributions of reduced and sulfided cobalt species are obtained.
