Abstract: A process is disclosed for reactivating an agglomerated iridium-containing catalyst and particularly platinum-iridium 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.

Abstract: A process is disclosed for reactivating an agglomerated iridium-containing catalyst and particularly a platinum-iridium on alumina reforming catalyst. The process includes contacting an agglomerated catalyst with a reducing gas such as hydrogen to reduce agglomerated iridium oxides to the free metal, a hydrogen chloride pretreatment step to increase the chloride level of the catalyst to about 1.6 weight percent and above, and a redispersion step involving contacting with elemental oxygen. The process eliminates the need for gaseous chlorine in the redispersion feedstream. If no iridium oxides are initially present, the hydrogen reduction step is optional.

Abstract: Novel molybdenum oxycarbonitride compositions are described together with a general method of synthesis. The compositions can be obtained by the relatively low temperature thermal decomposition of an amine molybdate and can be amorphous, poorly crystalline, or substantially crystalline, and can unexpectedly possess high surface areas in the region of about 60 to 130 m.sup.2 /g and higher. The compositions have the general formula: MoO.sub.a C.sub.b N.sub.c, where a, b and c are non-zero decimal values and the sum: a+b+c, is less than or equal to about one, as evidenced by X-ray diffraction and chemical analyses. The compositions are useful as abrasives, as for removing oxide coatings from metals.

Abstract: A modified liquid-liquid extraction system is disclosed in which a particulate solid and a liquid, both insoluble in a second liquid, are mixed to form agglomerate particles which efficiently extract metal ions from dilute solutions.

Mixing energy is low, clean-up of effluent water is easily accomplished and metal values are readily stripped from the agglomerates by well-known techniques, such as treatment by aqueous acid solution.
