A PROCESS FOR THE ISOMERIZATION OF A FEEDSTREAM COMPRISING C5-C6 HYDIOCARBONS(10) WHERE THE PROCESS INVOLVES CHARGING HYDROGEN (11, 12) AND A FEEDSTREAM COMPRISING AT LEAST NORMAL C5-C6 HYDROCARBONS (10) INTO AN ISOMERIZATION ZONE (14) AND CONTACTING SAID HYDROGEN AND FEEDSTREAM WITH AN ISOMERIZATION CATALYST AT ISOMERIZATION CONDITIONS TO INCREASE THE BRANCHING OF THE FEEDSTREAM HYDROCARBONS AND PRODUCE AN ISOMERIZATION EFFLUENT STREAM (I 6) COMPRISING AT LEAST NORMAL PENTANE, NORMAL HEXANE, METHYLBUTANE, DIMETHYLBUTANE, AND METHYLPENTANE HAS BEEN DISCOVERED. WITHOUT PASSINGH THROUGH A STABILIZER, THE ISOMERIZATION EFFLUENT STREAM(16) IS PASSED TO A DEISOHEXANIZER ZONE (24) TO GENERATE AT LEAST A STREAM ENRICHED IN METHYLBUTANE AND DIMETHYLBUTANES (28). THE STREAM ENRICHED IN METHYLBUTANE AND DIMETHYLBUTANES (28) IS PASSED TO AN ISOMERATE STRIPER COLUMN (434)TO REMOVE BUTANE AND LIGHTER HYDROCARBONS AND GASSES. THE REMAINDER CONTAINING THE METHYLBUTANE AND DIMETHYLBUTANES (28) IS COLLECTED FOR USE IN, FOR EXAMPLE, -GASOLINE BLENDING.
