Robert T. Rozmiarek has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8834587
    Abstract: Reactor systems and methods are provided for the catalytic conversion of liquid feedstocks to synthesis gases and other noncondensable gaseous products. The reactor systems include a heat exchange reactor configured to allow the liquid feedstock and gas product to flow concurrently in a downflow direction. The reactor systems and methods are particularly useful for producing hydrogen and light hydrocarbons from biomass-derived oxygenated hydrocarbons using aqueous phase reforming. The generated gases may find used as a fuel source for energy generation via PEM fuel cells, solid-oxide fuel cells, internal combustion engines, or gas turbine gensets, or used in other chemical processes to produce additional products. The gaseous products may also be collected for later use or distribution.
    Type: Grant

  • Patent number: 8696771
    Abstract: A compact integrated combustion reactor is described. In a preferred embodiment, the combustion catalyst is disposed in a staggered configuration such that the hot spot in an adjacent endothermic reaction chamber is substantially less than would occur with a conventional, unstaggered configuration. The integrated reactor may also include a methanation chamber for methanation of a reformate product. Systems containing reactant and product streams, and methods of conducting integrated combustion reactions are also described. A staggered catalyst conformation can be used more broadly for thermal chemical reactions requiring heat transfer in a layered device.

  • Patent number: 7744751
    Abstract: The present invention provides a process for producing reagents for a chemical reaction by introducing a fuel containing hydrocarbons into a flash distillation process wherein the fuel is separated into a first component having a lower average molecular weight and a second component having a higher average molecular weight. The first component is then reformed to produce synthesis gas wherein the synthesis gas is reacted catalytically to produce the desire reagent.
