IN A PROCESS FOR THE SELECTIVE HYDROGENATION OF MONO- AND DIOLEFINS IN A GASOLINE BOILING RANGE HYDROCARBON CONTAINING THE SAME AND AROMATIC HYDROCARBONS, THE IMPROVEMENT WHICH COMRPISES, IN A FIRST HYDROGENATION STAGE TRICKLING THE DYDROCARBON IN THE LIQUID PHASE THROUGH A FIXED BED OF SOLID HYDROGENATION CATALYST AT A TEMPERATURE BELOW 100*C., SAID HYDROGENTATION CATALYST COMPRISING ANOBLE METAL CATALYST ON A MACRO-POROUS SUPPORT HAVING AN INTERNAL SURFACE OF LESS THAN 100M.2/G. AND A WATER ABSORPTION CAPACITY OF AT EAST 10%, AND THEREAFTER IN A SECOND HYDROGENATION STAGE TRICKLING THE HYDROCARBON IN THE LIQUID PHASE THROUGH A FIXED BED OF SOLID NOBLE METAL HYDROGENTATION CATALYST AT A TEMPERATURE BETWEEN ABOUT 125 AND 250*C.
