The replacement of chromite catalysts in the selective vapor phase hydrogenation of maleic anhydride (MA) to y-butyrolactone (GBL), useful intermediate in the production of chlorine-free solvents, was investigated. In order to avoid the interferences related to physical dishomogeneity of the precurs
