CATALIZZATORE DI IDROGENAZIONE, PROCEDIMENTO PER LA SUA PREPARAZIONE ED IMPIEGO, PARTICOLARMENTE PER L'DROGENAZIONE E/O IDROGENOLISI DI CARBOIDRATI E POLIOLI

摘要

A metallic catalyst composition on an inert support, suitable in particular for hydrogenolysis reactions of higher polyhydric alcohols, which comprises the following relative to 100 parts of the catalyst: a) 0.5 to 5 weight % ruthenium; b) 1 to 10 weight % tin. The catalyst is used in particular for producing lower polyhydric alcohols such as ethanediol, propylene glycol, butanediol and glycerol, by means of hydrogenolysis reaction of higher polyhydric alcohols.
