  • Patent number: 6172124
    Abstract: A process for converting a hydrocarbon gas (e.g. natural gas) to syngas which, in turn, is converted into a liquid hydrocarbon product wherein a substantial amount of the heat generated in the process is recovered for use in generating steam needed in the process or for conversion into mechanical energy. Further, tail gas produced by the process is used to fuel the gas turbine which, in turn, is used power the compressors needed for compressing the air used in the process. By using tail gas to fuel the gas turbine, less of the compressed combustion-air is needed to cool the combustion gases in the turbine and, instead, can be used to provide a portion of the process-air required in the process; thereby possibly saving up to 20 to 30 percent of the horsepower otherwise needed to compress the required volume of process-air.

  • Patent number: 6172127
    Abstract: The invention herein relates to a process of preparing a novel polyimide foam having superior heat-resistance, flame retardancy, homogeneous size and distribution of cells, and low density, wherein a polyimide precursor in a granular form is prepared by means of using heterocyclic amine as catalyst and then foaming. According to the present invention, the preparing process of a polyimide foam comprises reacting aromatic carboxylic acid or the anhydrides thereof with an excess of aliphatic univalent alcohol to yield an aromatic ester solution. To the aromatic ester solution, divalent amines or the mixture thereof were added in the equivalent amount of said carboxylic acid or the anhydrides thereof in addition to a catalyst and surfactant to yield a polyimide.

  • Patent number: 6172128
    Abstract: Nanoporous polymeric materials are fabricated in which polymeric strands are crosslinked via ring structures. Preferred ring structures are formed de novo during crosslinking, and at least some of the ring structures are preferably included in the backbones of the strands. At least one of the ring structures may advantageously comprise an aromatic structure, and may more advantageously comprise a benzyl moiety. Especially preferred polymers comprise a poly(arylene ether) synthesized from a difluoroaromatic portion and an aromatic bisphenolic portion. In another preferred aspect, the difluoroaromatic portions of the poly(arylene ether) carry at least two different crosslinking functionalities. In an even more preferred aspect, the crosslinking functionalities comprise an ethynyl and a tetracyclone. Nanoporosity is preferably introduced by thermolyzing one or more thermolabile portions in the crosslinked polymer. An especially preferred thermolabile portion comprises ethylene glycol-poly(caprolactone).

  • Patent number: 6172139
    Abstract: A method for making a particulate filled polymeric matrix composite film includes mixing a polymeric matrix material with a dispersion of particulate filler in a carrier liquid to form a casting composition and adjusting the viscosity of the casting composition to retard separation of the particulate filler from the composition. A layer of the viscosity-adjusted casting composition is cast on a substrate and the layer is consolidated to form the particulate filled polymer matrix composite film. Films made by the method include very thin, e.g less than 1.0 mil, fluoropolymeric matrix films highly filled with very small diameter, preferably spherical, particles for use as, e.g. dielectric substrate materials in laminar electrical circuits.
