    Abstract: A method for producing a synthesis-gas product gas and a vapor stream includes catalytic steam reforming a hydrocarbonaceous feedstock in a steam reformer. The hot synthesis-gas product gas stream is cooled in a heat exchanger to form a cooled synthesis-gas product gas stream and a first partial vapor stream, which is supplied to the product vapor stream. The reforming furnace is operated so as to burn a burner feedstock in burners, cool a hot flue gas stream from the burners in a heat exchanger to form a cooled flue gas stream and a second partial vapor stream, and separate the cooled flue gas stream into a waste gas stream and a flue gas recirculation stream. The flow of the recirculated flue gas is increased with decreasing flow of the synthesis-gas product gas to obtain an approximately constant product vapor stream by increasing the second partial vapor stream.

    Abstract: Described herein are systems and methods for achieving fast pyrolysis of wood and other carbonaceous solids in rotary reactors. Novel heating, feeding and condensing methods result in high oil yields near those currently achieved with more complicated fast pyrolysis systems. High intensity burners are arranged and controlled to produce high heating rates and uniform temperature of the rotating cylindrical walls of the reactors. The feeding system delays the onset of pyrolysis until the solids fall onto the heated kiln walls. The pyrolysis gases and vapors are rapidly withdrawn and quenched with recycled liquids. The first condenser incorporates a clean out nozzle. Char products are readily separated and discharged into a heat exchanger where heat is recovered and used together with heat from reactor flue gas to dry the solids prior to being fed to the reactor.

  • Patent number: 8940061
    Abstract: An apparatus for generating hydrogen for fuel cells is provided. The apparatus includes a housing, a button, a first separating plate, a solid state reactant, and a separating membrane. The housing has an opening and a reservoir. The button connected to the housing covers the opening. The first separating plate disposed in the housing divides the reservoir into first and second sub-rooms. The opening communicates with the first sub-room and the first sub-room is suitable for storing a liquid reactant. The first separating plate has a through hole opposite to the button. The solid state reactant is disposed in the second sub-room. The separating membrane disposed on the through hole separates the first sub-room from the second sub-room. When the button is pushed, the button damages the separating membrane. Therefore, the liquid reactant flows to the second sub-room and reacts with the solid state reactant to generate hydrogen.

  • Patent number: 8932374
    Abstract: A method and equipment for producing hydrogen from biomass includes the stages of drying of the biomass, gasification of the biomass, and water gas shift reaction. The method further includes: subjecting the outgoing gases (CO2, N2 and H2O) from the gasification stage to a first heat exchange, wherein the outgoing gases are cooled; evaporating water with heat from outgoing gases; subjecting the steam to heat exchange wherein the steam is heated; reducing the steam to synthesis gas, wherein the synthesis gas is cooled and the air supply to the gasification is heated; separating the synthesis gas into a hydrogen stream and a carbon monoxide stream; reacting the carbon monoxide with water steam to carbon monoxide and hydrogen; separating also these secondary streams into a hydrogen stream and a carbon monoxide stream; and bringing together the primary and secondary hydrogen stream into a product stream.

  • Patent number: 8926941
    Abstract: The invention involves the use of a temperature swing adsorption process in steam methane reforming or autothermal reforming H2-production processes to capture CO2 and produce nearly pure off gas streams of CO2 for sequestration or enhanced oil recovery (EOR). The hydrogen stream output is substantially pure and can be recycled as a fuel to the steam methane reformer furnace or used in other petroleum and petrochemical processes.

  • Patent number: 8916128
    Abstract: The invention relates to an energetically self-sufficient syngas production method in at least one chemical loop. The chemical loop involves at least three distinct oxidation, reduction and gasification reaction zones: 1. at least one air-supplied oxidation reaction zone R1, referred to as “air” reactor, where the reaction of oxidation of the metallic oxides takes place after reduction, 2. at least one combustion reduction reaction zone R2, referred to as “fuel” reactor, where the feed combustion reaction takes place in the presence of the oxygen present in the metallic oxides, 3. at least one gasification reaction zone R3, referred to as “gasification” reactor, for gasification of the solid and/or liquid feeds in order to produce a syngas, said gasification being catalyzed by the at least partly reduced metallic oxides from R2.
