摘要：
The selective hydrogenation of cinnamaldehyde was studied on Al2O3 and L zeolites supported catalysts. The addition of Sn improves the selectivity to cinnamyl alcohol on Pt/Al2O3 catalysts while the reaction activity has a maximum at Sn/Pt atomic ratio of 0.5. It is interesting to find that Pt/L catalysts show both high activities and selectivities to carbonyl hydrogenated product cinnamyl alcohol. On Pt/RbL and Pt/SrL catalysts, the selectivities to cinnamyl alcohol are higher than 90% even with the cinnamaldehyde conversion of 95%. The effects of metal morphology, channel structures and basicities of L-zeolites are discussed. [GRAPHICS] Figure 1. Hydrogenation of cinnamaldehyde.
