METALLISCHE NICKELHYDRIERKATALYSATOREN, DEREN HERSTELLUNG UND DEREN VERWENDUNG

摘要

The catalyst can be prepared by reduction of a precursor of a hydrogenation-active metal, which may be present on an oxidic support, by reaction with at least one compound of the formula (I) H_nM(OR)_3-n (I) where M is Ga or Al, R is CR'₃ or SiR'₃ where R' is C_1-20-alkyl, and n is 1 or 2, or dimers or oligomers thereof, wherein the crystallite size of the hydrogenation-active metal in the finished catalyst is from 5 to 30, preferably 5 to 15 nm.
