摘要： A process for purifying a light hydrocarbon stream containing H 2 S is disclosed in which the selective catalytic partial oxidation of the H 2 S component is carried out while the hydrocarbon components slip through substantially unconverted. A catalyst that favors the partial oxidation of H 2 S over conversion of the hydrocarbon component of a gaseous H 2 S-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 H 2 S 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.

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 (30) for carrying out the catalytic partial oxidation of H2S, a second reaction zone for (40) the catalytic partial reduction of any incidental SO2 produced in the first reaction zone (30), and a cooling zone (320) including a sulfur condenser (380). 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 SO2is 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： 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.

摘要： A process and system for producing synthesis gas by a SPOC™ enhanced catalytic partial oxidation process is disclosed. A reaction in which H 2 S is partially oxidized to elemental sulfur and water takes place instead of a secondary reaction in which a portion of the light hydrocarbon feed is combusted to form CO 2 and water. An increase in yield and selectivity for CO and H 2 products results, and readily recoverable elemental sulfur is also produced.
