Different mass ratios of NI-CuAl2O3 catalyst were prepared by co-precipitation method, and characterized by XRD, TEM, BET, H2-TPR and other techniques. The results showed that the prepared catalyst has a nano-crystalline structure, a higher specific surface area and good reducibility.On this basis, we studied the catalytic performance of the catalyst for the liquid-phase hydrogenation of phthalic anhydride. The results showed that the catalyst has a high catalytic activity and selectivity, and high conversion rate and selectivity can be achieved under moderate reaction conditions.This study provides a foundation data and reference for further exploration of the liquid-phase synthesis technology based on NI-CuAl2O3 catalyst.Keywords: NI-CuAl2O3 catalyst; co-precipitation method; liquid-phase hydrogenation; catalytic performance.
