  • Patent number: 8926931
    Abstract: The present invention generally relates to a catalytic gasification of coal. Catalytic gasification of a Wyodak low-sulfur sub-bituminous coal from the Powder River Basin of Wyoming was investigated using an inexpensive sodium carbonate catalyst applied via incipient wetness impregnation. Experiments in an atmospheric pressure fixed-bed laboratory gasifier were performed to evaluate the effects of reaction temperature, feed gas steam content, and Na2CO3 loading on the catalytic gasification of the Wyodak coal. The temperature range investigated (700-900° C.) was selected with consideration of the Na2CO3 melting point (850° C.) to reduce the loss by volatilization of sodium. Sodium was found to be active during both pyrolysis and gasification steps. The catalyst was most cost-effective at addition levels of approximately 3 wt %. The random pore model provided a good fit to the conversion versus time data collected under both the catalytic and the uncatalytic conditions.

    Abstract: The invention is a process involving membrane-based gas separation for separating and recovering carbon dioxide emissions from combustion processes in partially concentrated form, and then transporting the carbon dioxide and using or storing it in a confined manner without concentrating it to high purity. The process of the invention involves building up the concentration of carbon dioxide in a gas flow loop between the combustion step and a membrane separation step. A portion of the carbon dioxide-enriched gas can then be withdrawn from this loop and transported, without the need to liquefy the gas or otherwise create a high-purity stream, to a destination where it is used or confined, preferably in an environmentally benign manner.

The system and method use inorganic capping agents that cap the surface of semiconductor nanocrystals to form photocatalytic capped colloidal nanocrystals, which may be deposited and oriented on a substrate to form an oriented photoactive material. The oriented photoactive material may be employed in the system to harvest sunlight and produce energy necessary for water splitting. The system may also include a light polarization system and elements necessary to collect, transfer, and store hydrogen and oxygen, for subsequent transformation into electrical energy.

  • Publication number: 20140166934
    Abstract: A method of generating syngas as a primary product from renewable feedstock, fossil fuels, or hazardous waste with the use of a cupola. The cupola operates selectably on inductive heat alone, chemically assisted heat, or plasma assisted heat. Additionally, the operation of the cupola is augmented by the use of direct acting carbon or graphite rods that carry electrical current for additional heat generation into the metal bath that is influenced by the inductive element. The method includes the steps of providing a cupola for containing a metal bath; and operating an inductive element to react with the metal bath. Feedstock in the form of a combination of fossil fuel, a hazardous waste, and a hazardous material is supplied to the cupola. A plasma torch operates on the metal bath selectably directly and indirectly. Steam, air, oxygen enriched air, and oxygen are supplied in selectable combinations.

  • Publication number: 20140158940
    Abstract: A method of producing a synthetic gas or a synthesis gas from a biosolid, such as dewatered sludge, that has a solids content that does not exceed 30 wt. %. The biomass having a solids content that does not exceed 30 wt. % is mixed with tar-rich materials and/or char particles, and optionally a bulking agent. The tar-rich materials and/or char particles may be a by-product of producing synthesis gas from a biomass such as refuse-derived fuels. The resulting mixture then is heated to provide a mixture having a solids content of at least 75 wt. %. The mixture having a solids content of at least 75 wt. % then is gasified under conditions to produce a synthetic gas rich in CO/CO2 or a synthesis gas rich in H2/CO.

  • Publication number: 20140106962
    Abstract: The present invention relates to methods for producing metal-supported thin layer skeletal catalyst structures, to methods for producing catalyst support structures without separately applying an intermediate washcoat layer, and to novel catalyst compositions produced by these methods. Catalyst precursors may be interdiffused with the underlying metal support then activated to create catalytically active skeletal alloy surfaces. The resulting metal-anchored skeletal layers provide increased conversion per geometric area compared to conversions from other types of supported alloy catalysts of similar bulk compositions, and provide resistance to activity loss when used under severe on-stream conditions. Particular compositions of the metal-supported skeletal catalyst alloy structures can be used for conventional steam methane reforming to produce syngas from natural gas and steam, for hydrodeoxygenation of pyrolysis bio-oils, and for other metal-catalyzed reactions inter alia.

    Abstract: A novel composition, system and method thereof for improving beam current during silicon ion implantation are provided. The silicon ion implant process involves utilizing a first silicon-based co-species and a second species. The second species is selected to have an ionization cross-section higher than that of the first silicon-based species at an operating arc voltage of an ion source utilized during generation and implantation of active silicon ions species. The active silicon ions produce an improved beam current characterized by maintaining or increasing the beam current level without incurring degradation of the ion source when compared to a beam current generated solely from SiF4.
