Abstract: A method and apparatus for the production of hydrogen-rich gas are provided. The method and apparatus prevent over-reduction of iron oxide-based shift catalyst by introducing an oxidative stream along with a carbon monoxide containing gaseous feed stream from a catalytic steam reformer to the catalyst bed region and thereby limits structural deterioration of the catalyst. Various sources may provide the oxidative stream including a shift catalyst bed region and a selective oxidation catalyst region.

Abstract: Method of making a product gas mixture comprising providing a first gas mixture, contacting the first gas mixture with a lean absorber liquid at a first pressure and absorbing a portion of the first gas mixture in the lean absorber liquid to provide a rich absorber liquid and a non-absorbed residual gas, pressurizing the rich absorber liquid provide a pressurized rich absorber liquid, stripping the pressurized rich absorber liquid with a stripping gas at a second pressure greater than the first pressure to provide a pressurized lean absorber liquid and the product gas mixture, and reducing the pressure of the pressurized lean absorber liquid to provide the lean absorber liquid at the first pressure.

Abstract: Reactive diluent fluid (22) is introduced into a stream of synthesis gas (or “syngas”) produced in a heat-generating unit such as a partial oxidation (“POX”) reactor (12) to cool the syngas and form a mixture of cooled syngas and reactive diluent fluid. Carbon dioxide and/or carbon components and/or hydrogen in the mixture of cooled syngas and reactive diluent fluid is reacted (26) with at least a portion of the reactive diluent fluid in the mixture to produce carbon monoxide-enriched and/or solid carbon depleted syngas which is fed into a secondary reformer unit (30) such as an enhanced heat transfer reformer in a heat exchange reformer process. An advantage of the invention is that problems with the mechanical integrity of the secondary unit arising from the high temperature of the syngas from the heat-generating unit are avoided.

Abstract: A system is set forth for the exothermic generation of soot depleted syngas comprising (i) reacting a hydrocarbon-containing fuel with an oxygen containing gas in a first reactor to produce the syngas and byproducts comprising CO2, H2O and soot; and (ii) introducing the syngas and byproducts into a second reactor containing a non-carbonaceous material that traps the soot for a sufficient time such that the majority of the byproduct soot is gasified via reaction with the byproduct CO2 and/or H2O to produce a syngas stream that is depleted in the soot. The system is particularly suitable for the practice of heat exchange reforming wherein a portion of the heat is recovered from the soot depleted syngas stream and used as at least a portion of the heat to facilitate the additional production of syngas via the (endothermic) catalytic reforming of natural gas and steam.

Abstract: A display module exhibition station includes a housing body, a bottom lid and a movable bracket. The bottom lid has one end pivotally engaged with the housing body to form an openable case. The movable bracket may hold a display module. The movable bracket is pivotally engaged with an inner side of the housing body and may be extended outside the openable case to exhibit the display module or house the display module inside the openable case to facilitate carrying of the exhibition station.

Abstract: An improvement to the process for separating dimethyl ether (DME) from byproducts in a one-step catalytic conversion of synthesis gas (syngas), the improvement comprising using a scrubbing solvent comprising a mixture of dimethyl ether and methanol for the separation of dimethyl ether and carbon dioxide from the unconverted synthesis gas in a scrubbing column. Additional improvements include recycling of the scrubbing solution, multi-step processing of the liquid effluent from the scrubber, and methods of processing the methanol-water effluent of the flash column that is interposed between the DME reactor and the scrubber.

Abstract: A process is set forth for converting synthesis gas into dimethyl ether (DME) in a single step comprising contacting the synthesis gas with a bifunctional catalyst system having a methanol synthesis functionality and a methanol dehydration functionality. In particular, the present invention is an improvement to said process for increasing the stability of the bifunctional catalyst system, particularly when the process is conducted in the liquid phase. The improvement comprises introducing a methanol containing stream into the DME reactor such that the methanol concentration throughout the DME reactor is maintained at a concentration greater than 1.0%, generally between 4.0% and 8.0%. In one embodiment of the present invention, the methanol containing stream comprises at least a portion of the byproduct methanol from the DME reactor such that said portion of byproduct methanol is introduced into the DME reactor as a recycle stream.

Abstract: The present invention pertains to a process for the coproduction of methanol and dimethyl ether (DME) directly from a synthesis gas in a single step (hereafter, the "single step DME process"). In this process, the synthesis gas comprising hydrogen and carbon oxides is contacted with a dual catalyst system comprising a physical mixture of a methanol synthesis catalyst and a methanol dehydration catalyst. The present invention is an improvement to this process for providing an active and stable catalyst system. The improvement comprises the use of an aluminum phosphate based catalyst as the methanol dehydration catalyst. Due to its moderate acidity, such a catalyst avoids the coke formation and catalyst interaction problems associated with the conventional dual catalyst systems taught for the single step DME process.

Abstract: The present invention is directed to a composition, its synthesis and a process for adsorptive separation of carbon monoxide from gas mixtures using adsorbents, which comprise cuprous compounds on amorphous oxide macroporous supports.
