A PROCESS FOR PREPARING A MOTOR FUEL OF IMPROVED OCTANE NUMBER FROM A NAPHTHA BOILING IN THE RANGE BETWEEN 100*F. AND 450*F. CONTAINING A SUBSTANTIAL PROPORTION OF IODINE-AROMATIZABLE COMPOUNDS WHICH COMPRISES SUBJECTING SAID NAPHTHA TO A HYDROCARBON CONVERSION PROCESS IN WHICH A SUBSTANTIAL PROPORTION OF HYDROCARBONS IS CONVERTED TO IODINE-RESISTANT HYDROCARBONS HAVING A HIGHER OCTANE NUMBER TO PRODUCE A PRODUCT CONTAINING IODINE-RESISTANT HYDROCARBONS OF HIGH OCTANE NUMBER AND IODINE-AROMATIZABLE HYDROCARBONS OF LOW OCTANE NUMBER AND THEN CONTACTING AT LEAST A PORTION OF SAID PRODUCT CONTAINING IODINE-AROMATIZABLE HYDROCARBONS AND AN EFFECTIVE TOTAL AMOUNT OF IODINE IN THE RANGE FROM 0.36 TO 1.2 STOICHIOMETRIC EQUIVALENTS, BASED ON SAID IODINE, AROMATIZABLE HYDROCARBNONS, AT A TEMPERATURE OF AT LEAST ABOUT 300*C. FOR A TIME IN THE RANGE BETWEEN 0.01 SECOND AND 5 MINUTES WHEREBY IODINEAROMATIZABLE HYDROCARBONS AND ELEMENTAL IODINE REACT TO FORM AROMATIC HYDROCARBONS AND HYDROGEN IODIDE, AND RECOVERING FROM THE REACTION PRODUCT A NAPHTHA OF INCREASED OCTANE NUMBER.
