Claim 1
Independent Claim
181 words
THE METHOD OF CONTINUOUSLY FORMING A MIXTURE OF CARBON MONOXIDE AND HYDROGEN IN EQUIMOLAR PROPORTIONS WHICH CONSISTS ESSENTIALLY IN CHARGING A MIXTURE OF METHANE, STEAM AND CARBON DIOXIDE TO A REFORMING ZONE CONTAINING A CATALYST WHICH IS ONE OF THE GROUP CONSISTING OF NICKEL AND IRON ON A CARRIER, MAINTAINING SAID REFORMING ZONE AT TEMPERATURES WITHIN THE RANGE OF FROM ABOUT 1300*F. TO 1800*F., ADJUSTING THE PROPORTIONS OF METHANE, STEAM AND CARBON DIOXIDE SO THAT THERE IS FROM 50-100 PER CENT EXCESS OXYGEN OVER THAT SATISFYING THE FOLLOWING EQUATION: CH4+CO2- ->2CO+2H2 BY ADDING ADDITIONAL CARBON DIOXIDE AND STEAM TO SUPPLY SUCH EXCESS OXYGEN SUCH ADDITIONAL CARBON DIOXIDE AND STEAM BEING PROPORTIONED IN THE RATIO OF FROM 1/2 TO MOLS OF CARBON DIOXIDE PER VOLUME OF STEAM FOR THE PURPOSE OF PRESERVING THE PRODUCT RATIO SHOWN IN THE ABOVE EQUATION, PERMITTING THE METHANE, STEAM AND CARBON DIOXIDE TO REMAIN RESIDENT IN THE REFORMING ZONE FOR A SUFFICIENT PERIOD OF TIME TO EFFECT THE DESIRED CONVERSION AND RECOVERING FROM SAID ZONE, A PRODUCT GAS CONTAINING ABOUT EQUAL VOLUMES OF CARBON MONOXIDE AND HYDROGEN.
