Abstract

Processes and apparatuses for regenerating catalyst particles are provided. The processes include introducing spent catalyst particles to a burn zone in a continuous catalyst regenerator. When introduced, the catalyst particles, which contain a platinum group metal, carry coke deposits. In the process, a combustion gas at a temperature of at least 490 DEG C with an oxygen content of at least 0.5 mol% is fed to the burn zone. There, the coke deposits on the catalyst particles are combusted with the combustion gas. The catalyst particles are passed from the burn zone to a halogenation zone in the continuous catalyst regenerator and the catalyst particles are oxyhalogenated to redisperse the platinum group metal to form regenerated catalyst particles.

Description

[0001] priority statement [0002] This application claims priority to US Application No. 13 / 163,336, filed June 17, 2011. field of invention [0003] The present invention relates generally to methods and apparatus for converting hydrocarbons to useful hydrocarbon products, and more particularly, to methods and apparatus for regenerating spent hydrocarbon conversion catalysts so that the catalysts can be reused in hydrocarbon conversion reactions. Background of the invention [0004] Catalytic processes for the conversion of hydrocarbons using platinum group metals and catalyst supports are well known and widely used. One such method is the catalytic reforming of petroleum refinery components, and the other is olefin production. Eventually, the catalysts used in these processes become deactivated due to the accumulation of coke deposits thereon, among other reasons. When the accumulation of coke deposits results in deactivation, the catalyst is regenerated or reconditione...
