摘要

Process for the hydrogenation of alquilaril ketones and for the preparation of a catalyst for hydrogenation catalyst, heterogeneous, and the use of phenolic compounds.The invention relates to a process for the hydrogenation of alquilaril ketones, which includes the contact of a feed comprising the alquilaril ketones and 0.5 to 30% by weight of phenolic compounds with hydrogen in the presence of a heterogeneous hydrogenation catalyst.The invention also relates to a process for the preparation of a catalyst with increased activity, and the use of phenolic compounds for the activation of catalysts for hydrogenation.
