    摘要: A compact sulfur recovery system is disclosed which comprises 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. 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. A process for recovering elemental sulfur from hydrogen sulfide-containing gas streams comprises regulating the temperature of certain components to favor the partial oxidation reaction, and the Claus reaction, as appropriate, and deters pooling of liquid sulfur on the Claus catalyst(s).

    摘要: The present invention includes a process for producing carbon filaments and synthesis gas from a mixture of alkanes, preferably natural gas, comprising converting a first portion of the alkanes, preferably C2+ hydrocarbons, directly to carbon filaments and converting a second portion of the alkanes, preferably methane, to syngas. The natural gas may be separated into a first feed stream comprising ethane, propane, and butane and a second feed stream comprising methane. The first feed stream is fed to a carbon filament CF reactor to produce carbon filaments and hydrogen. The second feed stream is fed to a syngas production reactor to produce syngas. Alternatively, the natural gas is fed to at least one carbon filament reactor that is maintained at an effective temperature to convert C2+ hydrocarbons in the natural gas to carbon filaments and hydrogen, thereby filtering methane from the natural gas.

    摘要: A new family of oxidative dehydrogenation catalysts having MCrAlY supports can be used in the production of olefins. Olefins are produced by heating a feed stream comprising at least an alkane and an oxidant to a temperature between 25° C. and 800° C.; contacting the feed stream with a catalyst comprising an MCrAlY structure and, optionally, a Group VIII promoter metal coating, wherein M is a base metal, or combination of base metals; and maintaining a contact time of the alkane with the catalyst of less than 200 milliseconds under conditions sufficient to achieve oxidative dehydrogenation of the alkane. M may comprise a metal selected from the group consisting of Group IB-VIIB metals, Group IIIA-VA metals, lanthanide metals, iron, cobalt, nickel, and combinations thereof. More particularly, M may comprise a metal selected from the group consisting Tb, Sm, Pr, Fe, Ni, Co, and combinations thereof.

    摘要: Enhanced mixed metal catalysts are provided which allow high conversions of carbon dioxide to methane, in some cases up to about 100% conversion. Methods of preparing enhanced mixed metal catalysts comprise a series of steps involving combining nickel and chromium salts with a nucleation promoter in a base environment to form a gel, allowing the gel to digest to form a solid and a mother liquor, isolating the solid, washing the solid, drying the solid, and thermally treating the solid to form a nickel-chromium catalyst. Methanation processes using the catalysts are also provided. The enhanced mixed metal catalysts provide more efficient conversion and lower operating temperatures for carbon dioxide methanation when compared to conventional methanation catalysts. Additionally, these enhanced catalyst formulations allow realization of higher value product from captured carbon dioxide.
