  • Patent number: 8308828
    Abstract: A steam reformer is use in a fuel processor system to create a water gas shift reaction between a hydrocarbon fuel and water. A hydrocarbon fuel and water are provided. The water is heated to superheated steam. The hydrocarbon fuel is mixed with the superheated steam to produce a vaporized fuel/steam mixture. The vaporized fuel/steam mixture is directed into a gap space between concentric tubes. The gap space between the separate surfaces is very small. Within this confined gap space, the outer concentric tube is heated to maintain a reaction temperature range that induces the water gas shift reaction. The water gas shift reaction produces reactant gases that include hydrogen gas and contaminant gases. At least some of the contaminant gases are burned to heat the gap space.
