Abstract:
The invention relates to a catalyst containing from 0.1 to 20 mass % rhenium and 0.05 to 10 mass % platinum in relation to the total mass thereof. The inventive method for producing a support for said catalyst consists in a) treating a support which can be eventually pre-treated with the aid of a solution of rhenium compound, b) drying and annealing said support at a temperature ranging from 80 to 600 DEG C, and c) impregnating the support with a solution of platinum compound and in drying it. The inventive method for producing alcohol by catalytic hydrogenation of carbonyl compound on said catalyst is also disclosed.
Abstract:
THE PRESENT INVENTION PROVIDES A CATALYST COMPRISING FROM 0.1 TO 20% BY WEIGHT OF RHENIUM AND FROM 0.05 TO 10% BY WEIGHT OF PLATINUM, BASED ON THE TOTAL MASS OF THE CATALYST, ON A SUPPORT, OBTAINABLE BY A PROCESS IN WHICH A) THE OPTIONALLY PRETREATED SUPPORT IS TREATED WITH A SOLUTION OF A RHENIUM COMPOUND,B) DRIED AND HEAT-TREATED IN A REDUCTIVE ATMOSPHERE AT FROM 80 TO 600°C, C) IMPREGNATED WITH A SOLUTION OF A PLATINUM COMPOUND AND DRIED AGAIN,AND ALSO A PROCESS FOR PREPARING ALCOHOLS BY CATALYTICALLY HYDROGENATING CARBONYL COMPOUNDS OVER THIS CATALYST.
Abstract:
A supported catalyst (I) containing 0.1-20 wt.% rhenium and 0.05-10 wt.% platinum (with respect to the total weight of the catalyst) is prepared by: (a) treatment of the optionally pretreated support with a solution of a rhenium compound; (b) drying and heating in a reducing atmosphere at 80-600 degreesC and; (c) impregnation with a solution of a platinum compound and drying. An Independent claim is also included for a process for the production of alcohols by catalytic hydrogenation of carbonyl compounds using the catalyst (I).
