  • Publication number: 20070297970
    Abstract: A compact sulfur recovery system is disclosed which includes an upflow orientation for the gases through a primary structure including a catalytic partial oxidation reaction zone, a first temperature-control zone, a first Claus catalytic reaction zone, a second temperature-control zone, a first liquid sulfur outlet, and a first effluent gas outlet. The upward flow of the gases puts the hottest gases in contact with the tubes and tube sheet in the waste heat boiler where there is greater confidence in having liquid water in most continuous therewith. In some embodiments, a secondary structure follows the primary structure and comprises a second Claus catalytic reaction zone, a third temperature-control zone, a second liquid sulfur outlet, and a second effluent gas outlet. One or more components of the system employ heat transfer enhancement material in the temperature-control zones, and one or more components deter accumulation of liquid sulfur in the Claus catalytic reaction zones.

  • Publication number: 20050181939
    Abstract: A method and apparatus for converting a hydrocarbon and oxygen containing gas feed stream to a product stream, such as syngas, including catalytically partially oxidizing the hydrocarbon feed stream over a catalyst bed. The catalyst bed has a downstream zone which is less resistant to flow than the upstream zone.

  • Publication number: 20050126956
    Abstract: The invention relates to methods for improving the octane number of a synthetic naphtha stream and optionally for producing olefins and/or solvents. In one embodiment, the method comprises aromatizing at least a portion of a synthetic naphtha stream to produce an aromatized hydrocarbon stream; and isomerizing at least a portion of the aromatized hydrocarbon stream to produce an isomerized aromatized hydrocarbon stream having a higher octane rating than the synthetic naphtha stream. Alternatively, the method comprises providing at least three synthetic naphtha cuts comprising a C4-C5 stream; a C6-C8 stream and a C9-C11 stream; aromatizing some of the C6-C8 stream to form an aromatized hydrocarbon stream with a higher octane number; steam cracking some of the C6-C8 stream and optionally the C9-C11 stream to form olefins; and selling some portions of C9-C11 stream as solvents. In preferred embodiments, the synthetic naphtha is derived from Fischer-Tropsch synthesis.

  • Publication number: 20050124841
    Abstract: The invention relates to a reactor comprising two reaction zones and processes for the production of alkenes from alkanes. A first reaction zone includes a combustion catalyst, and a second reaction zone comprises a heating zone in thermal contact with the first reaction zone. One process comprises generating heat and an effluent by the combustion of a fuel with oxygen in the first reaction zone; passing an alkane feed through the heating zone of the second reaction zone such that the alkane feed absorbs a sufficient amount of the heat generated in the first reaction zone to initiate the conversion of alkanes to alkenes in the second reaction zone. In other embodiments, the effluent comprises oxygen, and the second reaction zone excludes a catalyst; alternatively, the effluent is substantially free of oxygen, and the second reaction zone comprises a supplemental oxygen feed and may or may not include a catalyst.

  • Publication number: 20050112047
    Abstract: Lanthanide-promoted rhodium-containing supported catalysts that are active for catalyzing the net partial oxidation of methane to CO and H2 are disclosed, along with their manner of making and high efficiency processes for producing synthesis gas employing the new catalysts. A preferred catalyst comprises highly dispersed, high surface area rhodium on a granular zirconia support with an intermediate coating of a lanthanide metal and/or oxide thereof and is thermally conditioned during catalyst preparation. In a preferred syngas production process a stream of methane-containing gas and O2 is passed over a thermally conditioned, high surface area Rh/Sm/zirconia granular catalyst in a short contact time reactor to produce a mixture of carbon monoxide and hydrogen.

  • Publication number: 20050042163
    Abstract: Metal loaded carbon filaments and a process for making the same are provided. This process includes forming metal on carbon filaments produced from at least one carbon-containing compound, e.g., an alkane or an alkene. The metal may be formed on surfaces of previously formed carbon filaments by, for example, electroplating, impregnation, or chemical vapor deposition. Alternatively, the carbon filaments and the metal may be formed concurrently, resulting in the metal being incorporated in the carbon filaments. An article of manufacture is also provided that includes a carbon filament having metal disposed thereon. The article of manufacture may be, for example, a high surface area catalyst, an electronic element, and a composite material having enhanced electrical properties.
