A carboxylic acid hydrogenation catalyst preparation method and application

The present invention relates to a carboxylic acid hydrogenation catalyst comprising the catalyst support, cobalt, alkaline earth metal element, IB group elements, wherein the content of cobalt accounts for 15wt% ~ 50wt% of the total weight of the catalyst, the content of alkaline earth metal element accounts catalyst total weight of 1wt% ~ 30wt%, the content of the group IB elements representing 0.1wt% ~ 15.0wt% of the total weight of the catalyst, the carrier is an oxide, an amount of from 10wt% ~ 80wt% of the total weight of the catalyst. The high catalyst activity, high selectivity of desired product; relatively low manufacturing cost; milder reaction conditions.
