Abstract 1. A PROCESS FOR THE PREPARATION OF HYDROGEN AND CARBON DIOXIDE WHICH COMPRISES (A) CONTACTING CARBON MONOXIDE AND STREAM WITH A CHROMIA-PROMOTED FERRIC OXIDE CATALYST TO FORM A REACTION MIXTURE, SAID CONTACTING BEING CONDUCTED AT A TEMPERATURE ABOVE THE BEW POINT TEMPERATURE OF THE REACTION MIXTURE AND IN THE RANGE OF ABOUT 600* TO ABOUT 1000* F. AND A PRESSURE BELOW THE DEW POINT PRESSURE OF THE REACTION MIXTURE AND IN THE RANGE OF ABOUT ATMOSPHERIC TO ABOUT 3000 P.S.I.G.; AND (B) CONTACTING AT LEAST A PORTION OF THE EFFUENT FROM STEP (A) AT A TEMPERATURE ABOVE THE DEW POINT TEMPERATURE OF THE REACTION MIXTURE AND VARYING FROM ABOUT 200* TO 700* F. AND AT A PRESSURE BELOW THE DEW POINT PRESSURE OF THE REACTION MIXTURE AND RANGING FROM ABOUT ATMOSPHERIC TO ABOUT 3000 P.S.I.G. WITH A CATALYST COMPRISING (I) AN ALKALI METAL COMPOUND DERIVED FROM AN ACIDIC HAVING AN IONIZATION CONSTANT OF LESS THAN ABOUT 1X10-3, AND (II) A HYDROGENATION-DEHYDROGENATION COMPONENT SELECTED FROM THE GROUP CONSISTING OF (A) A METAL COMPOSITION COMPRISING VANADIUM, MOLYBDENUM, TUNGSTEN, COBALT, TANTALUM OR NIOBIUM MATERIALS OR MIXTURES THEREOF OR (B) MIXTURES OF MATERIALS COMPRISING A VANADIUM, MOLYBDENUM, TUNGSTEN, COBALT, TANTALUM OR NIOBIUMM MATERIALS OR MIXTURES THEREOF WITH A NICKEL, IRON OR CHROMIUM MATERIAL OR MIXTURES THEREOF, THE WEIGHT RATIO OF SAID HYDROGENERATION-DEHYDROGENATION COMPONENT TO SAID ALKALI METAL COMPOUND, EACH CALCUATED ON THE BASIS OF THE OXIDES THEREOF, BEING LESS THAN 5:1.
