Claim 1
Independent Claim

AN IMPROVED PROCESS FOR PRODUCING ORGANIC COMPOUNDS FROM NORMALLY GASEOUS HYDROCARBONS WHICH COMPRISES REACTING A CARBONACEOUS FEED WITH OXYGEN IN A FIRST CONVERSION ZONE UNDER CONDITIONS TO PRODUCE THE GASEOUS EFFLUENT COMPRISING HYDROGEN AND OXIDES OF CARBON IN A MOL RATIO LESS THAN ABOUT 2:1, PASSING SAID GASEOUS EFFLUENT FROM SAID FIRST CONVERSION ZONE TO A FIRST SYNTHESIS REACTION ZONE UNDER CONDITIONS SUCH THAT HYDROGEN AND AN OXIDE OF CARBON ARE CONVERTED TO ORGANIC COMPOUNDS, SIMULTANEOUSLY REACTING A NORMALLY GASEOUS HYDROCARBON WITH STEAM IN A SECOND CONVERSION ZONE UNDER CONDITIONS TO PRODUCE A GASEOUS EFFLUENT COMPRISING HYDROGEN AND OXIDES OF CARBON IN A MOL RATIO GREATER THAN ABOUT 2:1, PASSING SAID EFFLUENT FROM SAID SECOND CONVERSION ZONE TO A SECOND SYNTHESIS REACTION ZONE UNDER CONDITIONS SUCH THAT HYDROGEN AND AN OXIDE OF CARBON ARE CONVERTED TO ORGANIC COMPOUNDS RECYCLING NORMALLY GASEOUS COMPONENTS OF THE EFFLUENT FROM SAID FIRST SYNTHESIS REACTION ZONE TO SAID SECOND CONVERSION ZONE, AND RECYCLING NORMALLY GASEOUS COMPOUNDS FROM SAID SECOND SYNTHESIS REACTION ZONE TO SAID FIRST CONVERSION ZONE.

Claim 3
Dependent Claim
133 words
IN THE PROCESS WHEREIN GASES COMPRISING CARBON MONOXIDE AND HYDROGEN IN HYDROCARBON SYNTHESIS PROPORTIONS ARE GENERATED IN A SYNTHESIS GAS GENERATION ZONE, AND WHEREIN SAID GASES ARE REACTED UNDER HYDROCARBON SYNTHESIS CONDITIONS IN THE PRESENCE OF AN IRON TYPE HYDROCARBON SYNTHESIS CATALYST IN A HYDROCARBON SYNTHESIS REACTION ZONE, AND WHEREIN THE GASEOUS REACTION PRODDUCT OF THE REACTION BETWEEN HYDROGEN AND CARBON MONOXIDE COMPRISES CARBON DIOXIDE, THE STEPS COMPRISING SCRUBBING AT LEAST A PORTION OF SAID GASEOUS REACTION PRODUCT WITH A SOLVENT FOR CARBON DIOXIDE, COUNTERCURRENTLY CONTACTING THE SOLUTION THUS OBTAINED WITH NATURAL GAS AS A STRIPPING GAS WHEREBY CARBON DIOXIDE IS STRIPPED FROM SAID SOLUTION, PASSING AT LEAST A PORTION OF SAID STRIPPING GAS CONTAINING STRIPPED CARBON DIOXIDE TO SAID PROCESS AND CONVERTING SAID STRIPPING GAS AND SAID CARBON DIOXIDE IN SAID PROCESS.
