Title:
Reduction catalyst
Document Type and Number:
Japanese Patent JP6200946
Kind Code:
B2
Abstract:
Disclosed are catalysts comprised of platinum and rhodium on a support selected from the group of zirconia, stabilized (doped) zirconia, zirconia-metal oxide composites, and mixtures thereof, wherein the outer surfaces of the support are selected from the group of zirconia, stabilized zirconia, and mixtures thereof. More particularly, the supported catalysts comprise platinum and rhodium, wherein the molar ratio of platinum to rhodium is in the range of about 3:1 to about 1:2. The average pore diameter of the catalyst supports is in the range of about 5 nm to about 70 nm and the surface area is in the range of about 15 m2/g to about 200 m2/g. Also disclosed are methods for the hydrodeoxygenation of carboxylic acids, mono- and/or di-lactones thereof having at least one hydroxyl group on the backbone thereof to corresponding acids where the backbone hydroxyl group has been reduced in the presence of the catalyst.
