ABSTRACT:
The present invention pertains to a process for the hydrogenation of alkylaryl ketones, which process involves contacting a feed containing the alkylaryl ketones and from 0.5% to 30% by weight of phenolic compounds with hydrogen in the presence of a heterogeneous hydrogenation catalyst. The invention further relates to a process for preparing a hydrogenation catalyst with improved activity.
