    摘要: A method for generating syngas having a H2:CO ratio of less than 2:1 including selecting a predetermined desired syngas H2:CO molar ratio, selecting a hydrocarbon with a natural H2:CO molar ratio less than the desired ratio, selecting a hydrocarbon with a natural H2:CO molar ratio greater than the desired ratio, mixing the two hydrocarbons such that the natural H2:CO molar ratio of the mixture is the desired ratio, and catalytically partially oxidizing the mixture to produce syngas with the desired ratio.

    摘要: A multistage oxygen-added catalytic partial oxidation process and apparatus for converting H2S in an acid gas stream to elemental sulfur and water are disclosed. Each staged addition of oxygen or air at the top of the catalyst bed and at points along the catalyst bed maintain oxygen-limited H2S catalytic partial oxidation conditions whereby incidental SO2 production is minimized.

    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.

    摘要: A process for purifying a light hydrocarbon stream containing H2S is disclosed in which the selective catalytic partial oxidation of the H2S component is carried out while the hydrocarbon components slip through substantially unconverted. A catalyst that favors the partial oxidation of H2S over conversion of the hydrocarbon component of a gaseous H2S-light hydrocarbon mixture is employed. Apparatus for selectively cleaning up light hydrocarbon streams containing low concentrations (e.g., less than 25 vol. %), and apparatus for selectively cleaning up light hydrocarbon streams having higher concentrations (e.g., greater than 25 vol. %) of H2S are also disclosed.

    摘要: The disclosed sulfur recovery system and process avoid some of the operational problems of conventional Claus plants and processes by replacing the reaction burner and furnace tube of a conventional Claus plant with a more efficient short contact time catalytic reactor assembly containing a SPOC™ catalyst that operates efficiently at elevated temperatures. Such Claus plant modification also reduces or avoids the negative effects of hydrocarbons, CO2 and ammonia in Claus sulfur plant feeds, and permits efficient processing of dilute to concentrated H2S feeds. The disclosed modification makes possible the expansion of Claus plant capacity at lower cost.
