text: Process of making gas mixture principally containing hydrogen and nitrogen by the continuous reforming of naphtha which comprises vaporizing a liquid naphtha feed stream, preheating the resulting vaporized naphtha to a temperature of 400 F. to 800 F., preheating air and superheating steam, combining said streams of naphtha, steam and air to form a mixed gaseous stream at a temperature of 1400 F. to 1700 F. and pressure in the range of 100 to 300 p.s.i.g., said mixed gaseous stream having a steam/ carbon molar ratio between 5 to 1 and 7 to 1 and containing at least 125 standard cubic feet of air per liquid feed stream gallon of naptha, reacting said mixture non-catalytically for a time interval between 0.05 to 0.33 second, whereby said naphtha is simultaneously oxidized, cracked and reformed without accumulation of free carbon, and catalytically reforming the resulting gas mixture in contact with an externally heated reform catalyst selected from the group consisting of nickel and cobalt deposited on a carrier, said catalyst being maintained at a reaction temperature of at least 1600 F., said gas mixture having a linear gas velocity in the range of 10 to 30 ft./sec.
