Abstract

Copper-silicon，copper-chromium and copper-zinc composite oxide catalysts with different compositions were prepared by coprecipitation method.The physicochemical properties and pore structure of the copper-based composite oxide catalysts were characterized by X-ray diffraction（XRD），temperature-programmed reduction by H2（H2-TPR），N2 adsorption-desorption（BET） and potentiometric titration with n-butylamine.The hydrogenation of 2-propyl-2-heptenal catalyzed by the three copper-based composite oxide catalysts with different compositions in trickle bed and fixed bubbling bed was investigated.The results showed that there was no positive correlation between the difference of copper crystal size and surface acid content on the three copper-based composite oxide catalysts and the catalytic performance of 2-propyl-2-heptenal hydrogenation.The fixed bubbling bed reactor was better than trickle bed reactor for olefin aldehyde hydrogenation catalyzed by catalysts with abundant macropore.

Key words： olefin aldehyde; hydrogenation; trickle bed reactor; fixed bubbling bed; copper-based catalyst
