    摘要： A process is disclosed for reactivating an agglomerated iridium and selenium containing catalyst and particularly platinum-iridium-selenium on alumina reforming catalysts. The process includes contacting a substantially decoked agglomerated catalyst with a reducing gas such as hydrogen to reduce agglomerated iridium oxides present to the free metal, a hydrogen halide pretreatment step to increase the halogen level of the catalyst to about 1.3 weight percent and above, and a redispersion step involving hydrogen halide and elemental oxygen. Use of hydrogen halide and elemental oxygen in the redispersion treatment eliminates the need for use of elemental chlorine gas. If no iridium oxides are initially present, the hydrogen reduction step is optional.

    摘要： Biomass is used as a co-feed for a heavy petroleum oil coking process to improve the operation of the coking process and to utilize biomaterial for the production of transportation fuels. The coking process may be a delayed coking process or a fluidized bed coking process and in each case, the presence of the biomass will decrease the coke drying time so reducing coke handling problems in the unit besides forming a superior coke product. In the case of a fluidized bed coking process using a gasifier for the coke, the addition of an alkali metal salt improves the operation of the gasifier.

    摘要： The present invention relates to an improved exhaust gas cleaning system and method for a combustion source comprising a hydrogen generation system, a sulfur oxides trap, and a nitrogen storage reduction (NSR) catalyst trap. The improved exhaust gas cleaning system and method of the present invention also provides for a water-gas-shift catalyst between the sulfur oxides trap and the NSR catalyst trap, and a clean-up catalyst downstream of the NSR catalyst trap. The invention provides also a sulfur trap regenerable at moderate temperatures with rich pulses, rather than at high temperatures. The improved exhaust gas cleaning system of the present invention provides for the sulfur released from the sulfur trap to pass through the nitrogen oxide trap with no or little poisoning of NOx storage and reduction sites, which significantly improves NSR catalyst trap lifetime and performance to meet future emissions standards. The disclosed exhaust gas cleaning systems are suitable for use in internal combustion engines (e.g., diesel, gasoline, CNG) which operate with lean air/fuel ratios over most of the operating period.
