摘要： The present invention is directed toward improved processes for the regeneration of noble metal-containing catalysts wherein iron contamination of the catalyst during regeneration is significantly diminished. It has been found that maintenance of any iron present in contact with the catalyst in the oxidized state (e.g., as Fe.sub.2 O.sub.3 or Fe.sub.3 O.sub.4) during contact of the catalyst with a source of halogen in the regeneration haliding step results in a marked decrease in the degree of catalyst contamination by iron species.

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： A process is disclosed for reactivating agglomerated iridium-containing catalysts, in series, and particularly platinum-iridium 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 halide pretreatment step to increase the halide level of the catalyst to about 1.3 weight percent and above, a halogen/water vapor redispersion step at elevated temperature and a contacting of a second catalyst, in series, with the halogen/water vapor effluent at elevated temperature to partially burn-off the carbon deposits on the catalyst surface. Utilizing the effluent halogen stream, rather than subjecting to a scrubbing operation represents a savings in process costs, minimizes pollution problems and provides additional halogen protection to subsequent catalyst reactors in the process scheme.

摘要： The instant invention relates to novel compositions comprising highly dispersed Group VIII metal-phosphorus compounds or Group VIII metal-arsenic compounds supported on a high surface area solid support selected from the group consisting of carbon, alumina, silica, silica-alumina, zeolite, kieselguhr, vermiculite, and the refractory oxides of Group IVb and Vb, transition metals, and mixtures thereof.The instant invention further relates to a method for the preparation of the above compositions. In the preparation of the supported Group VIII metal-phosphorus compounds, the support is impregnated with both a phosphorus source, e.g. elemental phosphorus or a water soluble phosphorus salt, and a Group VIII metal source. The Group VIII metal source is impregnated onto the support from a solution of a water soluble Group VIII metal salt. Reduction of the resultant impregnated composition at temperatures above about 200.degree. C. results in the formation of highly dispersed, supported Group VIII metal-phosphorus compounds. The preparation of the highly dispersed supported Group VIII metal-arsenic compounds is accomplished in a similar manner. The Group VIII metal loading of these compositions range from about 0.1% to about 30 wt. % of the total catalyst. The phosphorus to Group VIII metal atomic ratio or the arsenic to Group VIII metal atomic ratio ranges from 0.3 to 3.0.The highly dispersed supported Group VIII metal-phosphorus compounds or Group VIII metal-arsenic compounds may be used to form highly dispersed, supported Group VIII metal catalysts after low temperature air calcination or decomposition in water at room temperature.
