Claim 1
Independent Claim
190 words
A METHOD FOR PRODUCING SYNTHESIS GAS WHICH COMPRISES THE STEPS OF DIVIDING A NATURAL GAS FEED STREAM INTO A FIRST PORTION AND A SECOND PORTION, CONTACTING THE FIRST PORTION IN ADMIXTURE WITH STEAM AND CARBON IOXIDE OBTAINED IN A LATER STEP AT AN ELEVATED TEMPERATURE WITHIN THE RANGE BETWEEN ABOUT 1100* AND 1850*F. AND AT PRESSURES FROM ABOUT 0 TO 300 POUNDS PER SQUARE INCH GUAGE IN A CONVERSION ZONE ARRANGED IN A COMBUSTION ZONE WITH A SYNTHESIS GAS CATALYST TO PRODUCE SYNTHESIS GAS, BURNING THE SECOND PORTION IN SAID COMBUSTION ZONE TO PROVIDE SAID ELEVATED TEMPERATURE AND TO FORM A COMBUSTION GAS CONTAINING SUBSTANTIAL AMOUNTS OF CARBON DIOXIDE, COOLING THE COMBUSTION GAS WITH WATER TO GENERATE STEAM AND REDUCE THE TEMPERATURE OF THE COMBUSTION GAS, RECOVERING CARBON DIOXIDE BY ABSORPTION FROM THE COOLED COMBUSTION GAS, ADMIXING THE STEAM AND RECOVERED CARBON DIOXIDE WITH THE FIRST PORTION, AND RECOVERING SAID SYNTHESIS GAS COMPRISING CARBON MONOXIDE AND HYDROGEN FROM THE CONTACTED ADMIXTURE, SAID FIRST AND SECOND PORTIONS BEING PROPORTIONED SUCH THAT THE HEAT RELEASED FROM BURNING SAID SECOND PORTION IS IN BALANCE WITH THAT REQUIRED FOR CONVERSION OF SAID FIRST PORTION.
