摘要：
A process for ring hydrogenation of a benzenepolycarboxylic acid or derivative thereof, includes contacting a feed stream comprising the acid or derivative thereof with a hydrogen containing gas in the presence of a catalyst under hydrogenation conditions to produce a hydrogenated product, wherein the catalyst contains rhodium and ruthenium.
