摘要： Metal migration from molecular sieve particles to binder particles in agglomerates of molecular sieves bearing group VIII zerovalent metal occurs readily at temperatures above 350.degree. C. Such migration can seriously impair the performance of the catalyst whose effectiveness depends on the presence of the metal largely, if not exclusively, on the molecular sieve particle. Exposure of the catalyst, or a catalyst precursor, to temperatures facilitating group VIII metal migration can occur at various periods during the catalyst's history. Group VIII metal migration can be inhibited and often effectively prevented when chlorine or a chlorine-containing compound is present in the non-reducing atmosphere at temperatures which otherwise would bring about metal migration.

摘要： A method is described for the regeneration of a hydrocarbon conversion catalyst that has become deactivated by carbonaceous material deposition where the catalyst comprises a nonacid zeolite and a Group VIII metal component. The method comprises the steps of (1) removing a substantial portion of the carbonaceous material from the catalyst by combustion with an oxygen-containing gas in the presence of a halogen, and (2) reducing the catalyst in the presence of hydrogen.
