Abstract
Copper-containing, multimetallic catalysts with either a zirconia or carbon support are described which have improved utility for the hydrogenolysis of a glycerol or glycerol-containing feedstock to provide a biobased 1,2-propanediol product. specially, improved carbon-supported examples of such catalysts are described for this reaction as well as for other processes wherein hydrogen is used, with methods for maintaining the activity of these catalysts. Related treatment methods in the preparation of these improved catalysts enable the use of carbons with a desired mechanical strength but which previously lacked activity, for example, for the conversion of a glycerol or glycerol-containing feed to produce 1,2-propanediol, so that copper-containing, multi-metallic catalysts may be employed for making a biobased propylene glycol using carbon supports that previously would have not been suitable.
