ABSTRACT:
Improved hydrogenation catalysts consisting essentially of reduced or at least partially reduced ruthenium and tin on a refractory oxide support which is insoluble in aqueous acid. Such catalysts are very durable and exhibit high conversion rates in aqueous acidic solution hydrogenation of hydrogenatable precursors (e.g. maleic acid, succinic acid, gamma-butyrolactone etc.) and high selectivity for their conversion to 1,4-butanediol and gamma-butyrolactone and their mixtures.
