Abstract

The application discloses a preparation method of a cerium oxide supported palladium catalyst and application of the catalyst in a solvent-free catalytic hydrogenation reaction of squalene, and belongs to the field of catalyst preparation and application. The catalyst takes cerium oxide as a carrier, and palladium is loaded through a deposition precipitation method to form a high-dispersion cerium oxide supported palladium catalytic system. The synergistic effect between the cerium oxide and the palladium significantly improves the hydrogenation efficiency and selectivity of the catalyst, and the catalyst is suitable for the catalytic hydrogenation reaction of squalene under a solvent-free condition. Compared with a traditional Pd / C catalyst, the prepared catalyst has higher activity, and the preparation method is simple, low in cost, and capable of efficiently catalyzing the hydrogenation of squalene under a solvent-free condition.
