    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 a reducing step involving contacting a decoked agglomerated catalyst with a reducing gas such as hydrogen to reduce agglomerated iridium oxides to the free metal, a hydrogen halide pretreatment step to provide a halide level to the catalyst of about 1.3 weight percent, and an elemental halogen/oxygen or wet oxygen redispersion step. The hydrogen halide pretreatment step is performed under elemental oxygen-free conditions prior to redispersion and allows high iridium redispersion values to be obtained. If no iridium oxides are initially present, the hydrogen step is optional.

    摘要： In a method of removing carbonyl sulfide from propylene by hydrolysis over a catalyst comprising platinum sulfide on alumina, the improvement comprising regenerating the catalyst by contacting the catalyst with a solvent for polypropylene under conditions such that any polypropylene on the catalyst will be readily dissolved. Specifically, the propylene is passed through, successively, a C.sub.3 -splitter, a heater, the platinum sulfide catalyst bed, and a topping still where resulting H.sub.2 S and CO.sub.2 are separated from the purified propylene. A preferred solvent is liquid propylene.

    摘要： Disclosed in a process by which consumption of sulfuric acid alkylation catalyst is decreased and alkylate yield is increased by reacting the hydrocarbon contaminats contained within spent alkylation acid with an isoparaffin to yield alkylate and sulfuric acid. Ultrasonic energy is utilized to obtain intense mixing to promote the reaction of the contaminats with the isoparaffin in the acid phase. The resulting dispersion is more stable that emulsions obtained from mechanical mixing and affords a high surface area between the hydrocarbon and acid phases for increased alkylate formation and acid regeneration.
