A METHOD FOR PRODUCING HYDROCARBON SYNTHESIS GAS WHICH COMPRISES PARTIALLY OXIDIZING A LOW-BOILING HYDROCARBON AT A TEMPERATURE OF AT LEAST ABOUT 1700* F. TO FORM A GASEOUS MIXTURE COMPRISING HYDROGEN AND CARBON MONOXIDE AS THE PRINCIPAL REACTION PRODUCTS, ADMIXING WITH SAID MIXTURE, AT A TEMPERATURE OF AT LEAST ABOUT 1700* F., STEAM AND CARBON DIOXIDE-CONTAINING EFFLUENT PRODUCTS FROM A SYNTHESIS REACTION FOR THE PRODUCTION OF HYDROCARBONS AND OXYGENATED ORGANIC COMPOUNDS FROM CARBON MONOXIDE AND HYDROGEN AND CONTACTING THE THUSFORMED MIXTURE WITH A REFORMING CATALYST AT A TEMPERATURE OF AT LEAST ABOUT 1250* F. WHEREBY STEAM AND ORGANIC COMPOUNDS OF SAID EFFLUENT PRODUCTS ARE CONVERTED TO ADDITIONAL HYDROGEN AND CARBON MONOXIDE.
