IMPROVED Ru, Re/CARBON CATALYST FOR HYDROGENATION IN AQUEOUS SOLUTION

摘要

Improved hydrogenation catalysts consisting essentially of highly dispersed, reduced ruthenium and rhenium on carbon support and methods of making and using the same. Such catalysts exhibit high conversion rates in aqueous solution hydrogenation of hydrogenatable precursors (e.g., maleic acid, succinic acid, gamma -butyrolactone, etc.) to tetrahydrofuran, 1,4-butanediol and mixtures thereof.
