Abstract

A flow cell was constructed to measure infrared spectra of catalyst samples with controlled heating at 673 K. We monitored sulfidation of an unsupported Co-Mo catalyst by thiophene. Correlation was found between the intensity changes and frequency shifts of the metal-oxygen IR bands and the appearance of oxythiomolybdate bands and the simultaneous increase of thiophene conversion. These results point to short-living cobalt-oxythiomolybdates which may have highest HDS activity.
