  • Patent number: 7931888
    Abstract: A method of producing a hydrogen product stream in which a steam stream is reacted with a hydrocarbon containing stream within a steam methane reformer. The resulting product stream is subjected to a water gas shift reaction and then to pressure swing adsorption to produce the hydrogen product stream. The hydrocarbon stream is alternatively formed from a first type of feed stream made up of natural gas, refinery off-gas, naphtha or synthetic natural gas or combinations thereof and a second type that is additionally made up of a hydrogen and carbon monoxide containing gas. During use of both of the types of feed streams, the flow rate of the steam stream is not substantially changed and reformer exit temperatures of both the reactant and the flue gas side are held essentially constant.

  • Publication number: 20110053020
    Abstract: Nanostructured catalysts and related methods are described. The nanostructured catalysts have a hierarchical structure that facilitates modification of the catalysts for use in particular reactions. Methods for generating hydrogen from a hydrogen-containing molecular species using a nanostructured catalyst are described. The hydrogen gas may be collected and stored, or the hydrogen gas may be collected and consumed for the generation of energy. Thus, the methods may be used as part of the operation of an energy-consuming device or system, e.g., an engine or a fuel cell. Methods for storing hydrogen by using a nanostructured catalyst to react a dehydrogenated molecular species with hydrogen gas to form a hydrogen-containing molecular species are also described.

    Abstract: A syngas cleanup section includes a water-gas shift reactor, a first operation unit and a second operation unit. The first operation unit includes a high permeance membrane with H2/CO2 selectivity in flow communication with the water-gas shift reactor to provide a H2-rich permeate stream and an H2-poor retentate stream. The second operation unit recovers H2 and CO from the retentate stream to produce a single, CO2-rich product stream, the entire content of which has a minimum pressure of at least about 10.0 bar. In one embodiment, the second operation unit includes a membrane with Knudsen selectivity for permeating H2, CO and CO2. In this embodiment, the permeate streams are combined to produce a H2 and CO-rich fuel stream used by a combined cycle power generation unit to produce electricity, and the retentate stream is sent to a catalytic oxidation unit to produce the CO2-rich product stream. In another embodiment, the second operation unit is the catalytic oxidation unit.

    Abstract: Disclosed are a method and a corresponding apparatus for converting a biomass reactant into synthesis gas. The method includes the steps of (1) heating biomass in a first molten liquid bath at a first temperature, wherein the first temperature is at least about 100° C., but less than the decomposition temperature of the biomass, wherein gas comprising water is evaporated and air is pressed from the biomass, thereby yielding dried biomass with minimal air content. (2) Recapturing the moisture evaporated from the biomass in step 1 for use in the process gas. (3) Heating the dried biomass in a second molten liquid bath at a second temperature, wherein the second temperature is sufficiently high to cause flash pyrolysis of the dried biomass, thereby yielding product gases, tar, and char. (4) Inserting recaptured steam into the process gas, which may optionally include external natural gas or hydrogen gas or recycled syngas for mixing and reforming with tar and non-condensable gases.
