Abstract
The liquid phase hydrogenation of succinic acid (SA) to ?-butyrolactone (GBL) and 1,4-butanediol (BDO) was investigated using ruthenium-cobalt bimetallic catalysts in a semi-batch slurry reactor. The doping of ruthenium (up to 1%) with cobalt resulted in increase (3-4 times) in the overall hydrogenation activity indicating a strong synergistic effect. Ru-Co bimetallic catalyst also influenced the product distribution by promoting specific hydrogenation steps in the overall reaction scheme. Based on the observed catalyst activity results, a speculative reaction pathway for cobalt as well as for ruthenium-cobalt catalyzed hydrogenation of succinic acid has been proposed.
