  • Patent number: 7504047
    Abstract: The invention disclosed is a method for improving the selectivity of a desired chemical reaction over an undesired chemical reaction utilizing a reactor having at least one channel having a catalyst positioned thereon and a presenting a reactant flow stream at a known flow rate and inlet temperature over the catalyst at a velocity such that a boundary layer formed thereby relative to said catalytic surface defines a thickness that is sufficiently less than the thickness of a fully developed boundary layer over said catalytic surface whereby the desired chemical reaction occurs preferentially over the undesired chemical reaction.

  • Patent number: 7476367
    Abstract: A stacked catalytic reactor is provided comprising of a plurality of housings, each housing defining a cavity having an entrance in fluid communication therewith, each housing further defining a plurality of first passages wherein each such first passage is in fluid communication with the cavity and each such first passage defines an exit. The plurality of housings are placed adjacent one to the other such that a second cavity and second passages are defined between successive housings, each second passage defines an exit, and the first passage exits and the second passage exits are interstratified and proximate one to the other. The stacked catalytic reactor employs backside cooling of a catalyst deposited therein in order to oxidize a fluid in the presence of a catalyst and transfer some heat of reaction into a second fluid and isolate the fluid to be reacted from the backside cooling fluid and then combine both fluids.

  • Patent number: 7343971
    Abstract: A method and system for dissociating methane hydrate deposits in-situ is provided wherein an oxidizer fluid and a supply of fuel, both at a pressure higher than that of the methane hydrate deposit, are supplied and delivered to the methane hydrate deposit. The fuel is combusted downhole by reacting it with the oxidizer fluid to provide combustion products. The combustion products are placed in contact with a diluent fluid to produce a heated product fluid. The heated product fluid is injected into the methane hydrate deposit whereby methane is dissociated from the methane hydrate and made available for extraction. In addition, carbon dioxide may be made available to promote the formation of carbon dioxide hydrates from the liberated methane hydrate water.

  • Patent number: 7141092
    Abstract: A method for regenerable adsorption includes providing a substrate that defines at least one layer of ultra short channel length mesh capable of conducting an electrical current therethrough, coating at least a portion of the substrate with a desired sorbent for trace contaminant control or CO2 sorption, resistively heating the substrate, and passing a flowstream through the substrate and in contact with the sorbent.

  • Patent number: 6752623
    Abstract: The present invention is a method, and an apparatus for practicing the method, that creates a product stream and a heat of reaction from a fuel-rich fuel/air mixture and then contacts the product stream with a sufficient quantity of additional air to completely combust all of the fuel, to which air a portion of the heat of reaction has been transferred.
