  • Publication number: 20110147665
    Abstract: Novel designs for microchannel apparatus are described in which microchannels are shaped to reduce the amount of material needed to build an apparatus. In these designs, some microchannels are shaped, in cross-section, to provide relatively more structural material in areas of greatest stress, while leaving greater area for unit operations in areas of the apparatus that are subjected to relatively less stress.

  • Patent number: 8100996
    Abstract: This invention relates to a process for converting a carbonaceous material to a desired product comprising one or more hydrocarbons or one or more alcohols, the process comprising: (A) gasifying the carbonaceous material at a temperature in excess of about 700° C. to form synthesis gas; and (B) flowing the synthesis gas in a microchannel reactor in contact with a catalyst to convert the synthesis gas to the desired product.

  • Patent number: 9893364
    Abstract: A new electroless plating approach to generate a porous metallic coating is described in which a metal is electrolessly deposited on a surface. Microparticles in the metal are removed to leave pores in the metal coating. Another method of forming electroless coatings is described in which a blocking ligand is attached to the surface, followed by a second coating step. The invention includes coatings and coated apparatus formed by methods of the invention. The invention also includes catalyst structures comprising a dense substrate and a porous metal adhered to the dense substrate, which is further characterized by one or more of the specified features.

  • Patent number: 7250151
    Abstract: Integrated Combustion Reactors (ICRS) and methods of making ICRs are described in which combustion chambers (or channels) are in direct thermal contact to reaction chambers for an endothermic reaction. Particular reactor designs are also described. Processes of conducting reactions in integrated combustion reactors are described and results presented. Some of these processes are characterized by unexpected and superior results, and/or results that can not be achieved with any prior art devices.

  • Patent number: 11618860
    Abstract: The present invention provides a process for the manufacture of a useful product from carbonaceous feedstock of fluctuating compositional characteristics, the process comprising the steps of: continuously providing the carbonaceous feedstock of fluctuating compositional characteristics to a gasification zone; gasifying the carbonaceous feedstock in the gasification zone to obtain raw synthesis gas; sequentially removing ammoniacal, sulphurous and carbon dioxide impurities from the raw synthesis gas to form desulphurised gas and recovering carbon dioxide in substantially pure form; converting at least a portion of the desulphurised synthesis gas to a useful product. Despite having selected a more energy intensive sub-process i.e. physical absorption for removal of acid gas impurities, the overall power requirement of the facility is lower on account of lower steam requirements and thereby leading to a decrease in the carbon intensity score for the facility.

  • Patent number: 7226574
    Abstract: A process is disclosed for converting a hydrocarbon reactant to a product comprising CO and H2. The process comprises: (A) flowing a reactant composition comprising the hydrocarbon reactant and oxygen or a source of oxygen through a microchannel reactor in contact with a catalyst under reaction conditions to form the product, the microchannel reactor comprising at least one process microchannel with the catalyst positioned within the process microchannel, the hydrocarbon reactant comprising methane, the contact time for the reactant composition within the process microchannel being up to about 500 milliseconds, the temperature of the reactant composition and product within the process microchannel being up to about 1150° C., the conversion of the hydrocarbon reactant to carbon oxide being at least about 50%. The product formed in step (A) may be converted to a product comprising CO2 and H2O in a microchannel reactor.
