Catalyst containing copper-zinc oxide-aluminum oxide, process for its preparation and use thereof for hydrogenation of aldehydes to alcohols

摘要

An unreduced catalyst which contains, per 100 parts by weight of CuO, 40 to 130 parts by weight of ZnO, 2 to 50 parts by weight of Al2O3 and, optionally, 0.5 to 8 parts by weight of an oxide of Mn, Mo, V, Zr and/or an alkaline earth metal, and, also optionally, 2 to 80 parts by weight of a support. The catalyst has a total BET surface area of 80 to 175 m2/g, 75% to 95% of the total BET surface area is formed by pores having a radius rp=15 nm. The invention further relates to a process for the production of the catalyst and its use for the hydrogenation of aldehydes.
