Cu-Zn/Al2O3 Catalyst for the Hydrogenation of Esters to Alcohols

Abstract

Abstract: A chromium free Cu-Zn/Al2O3 catalyst was used for the slurry phase hydrogenation of palm oil esters to alcohols. Optimal reaction conditions were given. Under the relatively mild conditions of 240 °C and 10 MPa hydrogen pressure, the alcohol yield was above 86.3%, which was much higher than that of conventional Cu-Cr catalysts. Phase changes of the precursor and the calcined and used catalysts were investigated. The role of the active components and surface hydroxyl groups was discussed.

Key words: copper, zinc, alumina, ester hydrogenation, high alcohol
