ABSTRACT:
Highly active and selective linolenate-reducing, copper catalysts are prepared by vacuum drying copper-silica coprecipitates, and then activating the precipitates by heat treatment. The resultant catalysts are characterized by activities 2-3.5 times those of commercial copper chromites and also possess comparable linolenate selectivities.
