Use of Simple Test Reactions to Characterise the Catalytic Activity of a Commercial CoO-MoO3-Al2O3 Catalyst

Exchange of thiophene with D2 and reactions of deuterium-labelled propene and isobutene, followed using a combination of mass spectometry and microwave spectroscopy, have been used to characterise the catalytic nature of a commercial CoO-MoO3-Al2O3 (CMA) catalyst.The results indicate that the activity of partially sulphided CMA, produced by exposure to H2S or by hydrodesulphurization (h.d.s.) of ethanethiol, closely resembles that of unsupported MoS2.Thus, sulphided-CMA shows high selectivity/activity for exchange of the α hydrogens in thiophene and catalyses double bond migration in propene through half-hydrogenated intermediates, activity characteristic of MoS2, whereas oxide-CMA is much less active for α exchange and shows Lewis acid type activity for the latter reaction.It appears that a CMA catalyst during h.d.s. may usefully be described as "dual-functional", with MoS2 supported on, and stabilised by, an acidic support.
