    Abstract: The invention relates to a method of reforming a gas containing tarry impurities, such as the gasification gas obtained by gasifying a fuel. In the method, oxygen or an oxygenous gas (10) is added to a gas flow (8), after which the gas is brought into contact with a solid catalyst (11, 12) at a high temperature. According to the invention, the reformation takes place in stages so that, in the first pre-reforming stage, the gas is brought into contact with a zirconium-based catalyst (11), such as zirconium oxide, for example, and, in the next stage, with a metal catalyst (12), such as metallic nickel. The two-stage reformation is used for preventing the deactivation of the metal catalyst and the formation of carbon deposits in the reforming reactor. The invention also includes the use of the zirconium compound in pre-reforming the tar-bearing gas to achieve the said goals.

  • Patent number: 7964176
    Abstract: Relates to a process and apparatus that improves the hydrogen production efficiency for small scale hydrogen production. According to one aspect, the process provides heat exchangers that are thermally integrated with the reaction steps such that heat generated by exothermic reactions, combustion and water gas shift, are arranged closely to the endothermic reaction, steam reformation, and heat sinks, cool natural gas, water and air, to minimize heat loss and maximize heat recovery. Effectively, this thermally integrated process eliminates excess piping throughout, reducing initial capital cost.

    Abstract: This invention discloses systems and methods for conversion of high moisture waste materials to dry or low moisture products for recycle or reuse. The equipment systems comprise a gas turbine generator unit (preferred heat source), a dryer vessel and a processing unit, wherein the connection between the gas turbine and the dryer vessel directs substantially all the gas turbine exhaust into the dryer vessel and substantially precludes the introduction of air into the dryer vessel and wherein the processing unit forms the dried material from the dryer vessel into granules, pellets or other desired form for the final product. Optionally, the systems and methods further provide for processing ventilation air from manufacturing facilities to reduce emissions therefrom.

  • Patent number: 7862633
    Abstract: A system and method for creating reformate with decreased carbon deposition. The system is made up of a steam source, a superheater, a fuel injection device, a prereformer, and a reformer with catalyst linings. The system functions to superheat steam while maintaining the fuel at a lower temperature prior to injection and mixing with the steam. After injection and mixing, the steam and fuel mixture is then passed through a prereformer where catalysts treat a portion of the fuel and steam mixture. After these portions are treated with a catalyst, the mixture is passed through to a reformer where further treatment of the material by catalyst takes place.

  • Patent number: 7815700
    Abstract: A device, system and method of mixing two fluids are described herein. A gaseous first fluid is distributed through a distribution zone to a mixing zone by a bundle of pipes parallel to an axis inside which the first fluid is uniformly distributed. A second fluid is uniformly distributed outside the pipes in the distribution zone. The mixing zone is separated from the distribution zone by a pipe-plate supporting the pipes. The pipe-plate has slits or openings to uniformly discharge the second fluid in an axial flow direction into the mixing zone. The pipes extend beyond the pipe-plate into the mixing zone to partialize an outlet flow of the first fluid. In one aspect, the pipes have different lengths to partialize the outlet flow. In another aspect, a terminal portion of the pipes partializes the outlet flow axially, radially, transversally or a combination thereof in the mixing zone.
