Abstract: A catalyst (I) comprises 0.01-50 wt.% rhenium and 0-20 wt.% of an additional metal comprising Zn, Cu, Ag, Au, Ni, Fe, Cr or V on an oxidatively pretreated activated carbon support. An independent claim is included for production of alcohols by catalytic hydrogenation of carbonyl compounds by means of a catalyst (I).

Abstract: A process is provided for the regeneration of a heterogeneous catalyst used for the preparation of compounds containing NH 2 groups by the hydrogenation, with hydrogen, of compounds containing at least one unsaturated carbon-nitrogen bond, wherein a) the feed of the compound to be hydrogenated is stopped and b) the heterogeneous catalyst is treated with a compound of the formula R 1 R 2 N-CO-R 3 (I), in which R 1 is hydrogen or C 1 -C 4 alkyl and R 2 , R 3 independently of one another are each hydrogen or C 1 -C 4 alkyl or together are a C 3 -C 6 alkylene group, or mixtures of such compounds, at a pressure ranging from 0.1 to 30 MPa and a temperature ranging from 100 to 300° C., with the proviso that the compound of formula (I) is in liquid form during the treatment.
