ABSTRACT:
A regeneration process for reconditioning catalyst particles containing platinum by transferring the catalyst particles through a combustion zone and a reconditioning zone is disclosed. Drying of the catalyst particles and redispersion of the platinum occur simultaneously in a single reconditioning zone. Catalyst that enters the reconditioning zone is contacted countercurrently with a heated gas stream containing chlorine and oxygen. A low moisture content of the gas stream aids drying and allows the equilibrium reaction between hydrogen chloride and oxygen on the one hand, and water and chlorine on the other hand to be shifted to chlorine. This shift of the equilibrium reaction can be further improved by maintaining an oxygen-enriched environment within the reconditioning zone. By eliminating the need for separate drying and redispersion zones used previously, the regeneration apparatus is less expensive to build and the regeneration process is less expensive to operate.
