    • 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. The catalysts are generally useful for the selective hydrodeoxygenation of carboxylic acids containing at least one additional hydroxyl group along the backbone thereof. More particularly, the catalysts are supported catalysts comprising 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 from about 5 nm to about 70 nm and the surface area is in the range of from about 15 m 2 /g to about 200 m 2 /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. Further disclosed is a process of producing an adipic acid product at a yield of at least about 80%.

    • The present disclosure relates generally to water concentration reduction processes within an adipic acid process. The present invention also includes process for converting a glucose-containing feed derived from a carbohydrate source to an adipic acid product wherein the process includes the steps of: converting glucose in the feed to a reaction product including a hydrodeoxygenation substrate and a first concentration of water; reducing the concentration of water in the reaction product to produce a feedstock including the hydrodeoxygenation substrate and second concentration of water, wherein the second concentration of water is less than the first concentration of water; and converting at least a portion of the hydrodeoxygenation substrate in the feedstock to an adipic acid product. Processes are also disclosed for producing hexamethylene diamine and caprolactam from the adipic acid product.
