Abstract

An illustrative method for converting hydrocarbon fuel to hydrogen rich gas, includes the steps of: reacting the hydrocarbon fuel with steam in the presence of reforming catalyst and a carbon dioxide fixing material to produce a first hydrogen gas; and removing carbon monoxide from the first hydrogen gas to produce the hydrogen rich gas, wherein the removing step utilizes a process selected from methanation or selective oxidation. In one illustrative embodiment the carbon dioxide fixing material is selected from calcium oxide, calcium hydroxide, strontium oxide, strontium hydroxide, allanite, andralite, ankerite, anorthite, aragoniter, calcite, dolomite, clinozoisite, huntite, hydrotalcite, lawsonite, meionite, strontianite, vaterite, jutnohorite, minrecordite, benstonite, olekminskite, nyerereite, natrofairchildite, farichildite, zemkorite, butschlite, shrtite, remondite, petersenite, calcioburbankite, burbankite, khanneshite, carboncernaite, brinkite, pryrauite, strontio dressenite, and similar such materials and any combination of these. The reforming catalyst in one preferred and illustrative embodiment is selected from nickel, platinum, rhodium, palladium, ruthenium, or similar supported reforming catalysts or combinations of these. In such instances the reforming catalyst is preferably supported on a high surface area support thus promoting the reforming reaction and more preferably is selected from alumina, titania, zirconia, or similar such compounds or combinations of these. It is preferred that in one illustrative embodiment that the temperature of the reacting step is from about 400.degree. C. to about 800.degree. C.
