A PROCESS FOR THE GASIFICATIN OF NAPHTHA TO PRODUCE A COMBUSTIBLE GAS WHICH COMPRISES VAPORIZING AND PREHEATING NAPHTHA TO A TEMPERATURE IN THE RANGE OF 112*F. TO 1000*F., SUPERHEATING STEAM, AND PREHEATING AIR; COMBINING SAID STREAMS OF NAPHTHA, STEAM AND AIR TO FORM A MIXED GASEOUS STREAM AT AN INITIAL TEMPERATURE OF AT LEAST 1000*F., SAID MIXED GASEOUS STREAM HAVING A STEAM TO CARBON MOLAR RATIO OF AT LEAST 1.5 AND AN AIR TO CARBON MOLAR RATIO OF AT LEAST 0.1, REACTING SAID MIXTURE FOR AN INTERVAL LESS THAN 1.0 SECOND WHEREBY THE PROCESS STREAM TEMPERATURE RISES TO A MINIMUM OF AT LEAST 1400* F. AND SAID NAPHTHA IS SIMULTANEOUSLY OXIDIZED, CRACKED AND PARTIALLY REFORMED WITHOUT ACCUMULATED DEPOSITION
