Au/Nb 2 O 5 and Au/CeO 2 catalysts were studied for the selective hydrogenation of crotonaldehyde, both in liquid (batch reactor, 4 atm, 60 8C, solvent: isopropanol) and in gas (flow microreactor, 120 8C, atmospheric pressure) phases. Samples were characterized by TPR and XRD and tested for the CO o
The effect of a previous oxidation treatment of the carbonaceous support on the catalytic behavior of platinum in the gas phase hydrogenation of crotonaldehyde (trans-2-butenal) over Pt/carbon black catalysts has been analyzed. Two heat-treated carbon blacks, one of them subjected to an oxidizing tr
