Synthesis of hydrocarbons

Claim 1

IN A PROCESS WHICH INVOLVES THE GENERATION AT A TEMPERATURE ABOVE ABOUT 1800* F. OF A SYNTHESIS GAS CONTAINING ESSENTIALLY HYDROGEN AND CARBON MONOXIDE IN A GAS GENERATION ZONE AND THE SUBSEQUENT CATALYTIC TREATMENT OF SAID SYNTHESIS GAS IN A SYNTHESIS REACTION ZONE AT A LOWER BUT ELEVATED TEMPERATURE IN THE PRESENCE OF A SYNTHESIS CATALYST EFFECTIVE TO CONVERT HYDROGEN AND CARBON MONOXIDE INTO DESIRED HYDROCARBONS, OXYGENATED HYDROCARBONS AND MIXTURES THEREOF, THE STEPS WHICH COMPRISE INJECTING HYDROCARBONS INTO THE HOT SYNTHESIS GAS FROM SAID GENERATOR AT A TEMPERATURE ABOVE ABOUT 1800* F. THEREBY HEATING THE INJECTED HYDROCARBONS TO A CRACKING TEMPERATURE AND EFFECTING SUBSTANTIAL CONVERSION OF SAID INJECTED HYDROCARBONS INTO HYDROCARBON PRODUCTS OF CRACKING, PASSING SAID SYNTHESIS GAS CONTAINING PRODUCTS OF CRACKING TO THE SYNTHESIS REACTION ZONE, EFFECTING SUBSTANTIAL CONVERSION THEREIN OF HYDROGEN AND CARBON MONOXIDE IN THE PRESENCE OF SAID PRODUCTS OF CRACKING INTO A DESIRED PRODUCT OF IMPROVED VALUE, AND REMOVING SAID PRODUCT FROM THE REACTION ZONE.
