Gas Phase Hydrogenation of Levulinic Acid to [gamma]-Valerolactone

Gas Phase Hydrogenation of Levulinic Acid to [gamma]-Valerolactone

The gas phase hydrogenation of levulinic acid to [gamma]-valerolactone over copper and ruthenium based catalysts in a continuous fixed-bed reactor system was investigated. Among the catalysts a copper oxide based one [50-75 % CuO, 20-25 % SiO.sub.2, 1-5 % graphite, 0.1-1 % CuCO.sub.3/Cu(OH).sub.2] g...

Zusammenfassung:The gas phase hydrogenation of levulinic acid to [gamma]-valerolactone over copper and ruthenium based catalysts in a continuous fixed-bed reactor system was investigated. Among the catalysts a copper oxide based one [50-75 % CuO, 20-25 % SiO.sub.2, 1-5 % graphite, 0.1-1 % CuCO.sub.3/Cu(OH).sub.2] gave [gamma]-valerolactone in 93 % yield for more than 90 h constant operation.
