Abstract:
A process for increasing the yield in high octane gasoline consisting of the steps of:(a) submitting a naptha feed to catalytic reforming in a catalytic reformer by contacting said feed with a catalytic reforming catalyst in order to form a reformed effluent consisting of light, intermediate and heavy fractions, the light fraction being rich in benzene;(b) separating said three factions in a separator into which the reformed effluent is directly introduced from the catalytic reformer, and recovering the intermediate fraction;(c) mixing the total amount of the light fraction rich in benzene from said separator with the total amount of the heavy fraction to form a mixture;(d) subjecting said mixture to a transalkylation system to form a second mixture having an increased intermediate fraction; and,(e) recycling the effluent coming from said transalkylation system into said separator and recovering additional intermediate fractions.
