The invention provides a process for the hydrogenation of the levulinic acid to gamma-valerolactone in a single step with a single Pt supported on hydrotalcite catalyst. The process provides conversion of gamma-valerolactone over Pt supported hydrotalcite catalyst at room temperature (250 C). The process provides a levulinic acid conversion of 34-100% with 20-50 bar hydrogen pressure to give gamma-valerolactone selectivity up to 99%.
