Preparation and characterization of NiO/HY catalyst

NiO/HY catalyst was prepared by impregnation method with the nickel acetate as the precursor and the HY as the carrier. The influences of impregnation solution acidity, the nickel species and the calcination process on the catalyst structure were studied by the nitrogen physical adsorption and XRD. The hydrogenation reaction of dicyclopentadiene (DCPD) was selected to evaluate the catalytic performance of the prepared catalyst. Experiments showed that the structure of the catalyst is critical to its performance, and NiO/HY catalyst has a good application prospect.
