Abstract: Gamma-valerolactone is prepared from a levulinic acid ester in a continuous process where a stream of the levulinic acid ester together with a gaseous stream of a hydrogen-containing gas is contacted with a hydrogenation catalyst, where the levulinic acid ester is in the liquid phase, and where the hydrogenation catalyst is a solid particulate catalyst including at least one hydrogenating metal, supported on an oxide carrier.
