REGENERATION OF METAL HALIDE CATALYST

摘要

A process for regenerating metal halide catalysts deactivated in hydroconversion of nitrogen-containing feedstocks by the formation of metal halide-ammonium halide complexes is disclosed. Regeneration is effected by contacting the complex with an electron donor solvent for metal halide at conditions at which the solvent effects decomposition of the complex and separation of the resultant metal halide and ammonium halide decomposition products by dissolving the metal halide.
