ABSTRACT:
Theta-alumina is a hydrothermally stable support which can be used advantageously as an inert carrier for metals effective as a hydrogenation catalyst, thereby affording means to conduct hydrogenation in aqueous media. Ruthenium on theta-alumina is especially effective in reducing aqueous solution of carbohydrates to their polyols with high conversion and, in the case of glucose, high selectivity to sorbitol.
