Liquid phase hydrogenation of crotonaldehyde over Au/CeO2 catalysts

Three Au/CeO2 catalysts, with different specific surface area (80, 150 and 240 m2/g) were tested for the hydrogenation of crotonaldehyde in liquid phase. Reactions were carried out with molecular hydrogen as the reductant, in a batch reactor using isopropanol as the solvent, at 80 8C and 1 MPa. The...

Under liquid phase the promotional effect of high surface area ceria is lost. The low and middle surface area samples (80 and 150 m2/g respectively) showed meager selectivity to carbonyl hydrogenation due to both the low promotional effect of the support and the relatively large size of gold particles.
