A CONTINUOUS PROCESS FOR THE MANUFACTURE OF A SUPPLEMENT GAS WHICH COMPRISES (1) MIXING A HYDROCARBON VAPOR WITH AIR AND STREAM IN PROPORTIONS SUCH THAT THE TOTAL OXYGEN CONTENT OF THE AIR AND STEAM IS AT LEAST SUFFICIENT TO FORM CARBON MONIXIDE WITH ALL OF THE CARBON IN THE HYDROCARBON VAPOR, (2) CONVERTING THE RESULTING MIXTURE TO A PRODUCER GAS-WATER GAS MIXTURE, IN THE PRESENCE OF AN EXTERNALLY HEATED CATALYST, BY CARRYING THE PRODUCER GAS AND WATER GAS REACTIONS SUBSTANTIALLY TO COMPLETION SO THAT THE METHANE CONTENT OF THE PRODUCT IS NOT MORE THAN ABOUT 8 VOLUME PER CENT AND THE CALCRIFIC VALUE OF THE PRODUCT IS NOT MORE THAN ABOUT 347 B. T. U. PER CUBIC FOOT, AND (3) MIXING SAID PRODUCT WITH A HYDROCARBON VAPOR IN SUCH PROPORTIONS AS TO PRODUCE A SUPPLEMENT GAS OF THE DESIRED CALORIFIC VALUE AND SPECIFIC GRAVITY.
