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.

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： 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. 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).
