ABSTRACT:
The invention provides an improvement in the partial nuclear hydrogenation of an aromatic hydrocarbon compound in the liquid phase with admixture of water catalyzed by a ruthenium-containing solid catalyst. The scope of the invention is in the use of a novel ruthenium-containing catalyst supported on a silica gel and the like carrier and the catalyst is prepared by the hydrolysis and gelation of an alkoxide of silicon or aluminum in a solution containing a ruthenium compound, e.g. ruthenium alkoxide, followed by drying of the gelled material so that the resultant catalyst is very uniformly impregnated with the ruthenium ingredient to be imparted with greatly improved catalytis activity and selectivity for the intended reaction over conventional ruthenium-containing catalysts prepared by post-impregnation of a preformed silica gel carrier.
