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： Apparatus and process for recovering elemental sulfur from a H2S-containing waste gas stream are disclosed. The apparatus preferably comprises a first reaction zone for carrying out the catalytic partial oxidation of H2S, a second reaction zone for the catalytic partial reduction of any incidental SO2 produced in the first reaction zone, and a cooling zone including a sulfur condenser. According to a preferred embodiment of the process, a mixture of H2S and O2 contacts a catalyst in the first reaction zone very briefly (i.e, less than about 200 milliseconds) producing primarily S0 and H2O. Some SO2 is also present in the first stage product gas mixture. A reductant gas (e.g. CO, or CH4 or natural gas) is fed together with the first stage product gas mixture to a second catalytic reaction zone where the partial reduction of the SO2 component to elemental sulfur and CO2 is carried out.

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.
