One-step Heterogeneous Catalytic Hydrogenating Esterification of Aldehyde and Acetic Acid over Pd-Ni/HZSM-5

Supported bi-metal Pt-Ni/HZSM-5 catalysts were prepared with impregnating method,and it was employed for heterogeneous catalytic one-step hydrogenating esterification of aldehyde and acetic acid.XRD results showed that Pt and Ni particles were highly dispersed on catalyst surface.Influences of Ni loading,temperature of calcinations,reduction and reaction,H2/aldehyde and amount of catalyst on catalytic performance were systematically investigated.The results demonstrated that the process technological conditions during preparing and reacting had considerable effect on catalytic performance.Catalytic performance was promoted ascribing to addition of platinum on Ni/HZSM-5.
