Palladium catalysts vanadium reduced

Pd-PVA catalyst reduced with a vanadous solution is quite interesting, as shown in Figure 6. The vanadium-reduced palladium (curve 2) not only converts benzaldehyde to benzyl alcohol at five times the rate of a hydrogen-reduced Pd-PVA catalyst but is also able to carry the reduction... [Pg.136]

The interaction of SO and an oxidizable hydrocarbon with the catalyst surface also illustrates how complex such behavior can be. In the oxidation of CH and SO, mixtures on vanadium, palladium/vanadium, and palladium cataly.sts, SO increased the CH oxidation rate on all catalysts.- How ever, SO, inhibited CO oxidation on the palladium/vanadium catalyst while it increased the CO oxidation rate on the vanadium catalyst. Also, SO, inhibits alkene oxidation on these types of catalysts as well. These results are explained by competition between SOj and the hydrocarbons for adsorbed forms of oxy gen on the catalyst surface. First, SO, can reduce the... [Pg.199]
