Patent ID: 8513149

Claim:
A process for drying regenerated catalyst in a continuous catalyst regeneration system, comprising: passing spent catalyst from a reactor to a regenerator; regenerating the catalyst through a combustion regeneration process in a combustion chamber, thereby creating catalyst effluent stream comprising a regenerated catalyst and a combustion gas comprising water; separating the regenerated catalyst from the combustion gas; passing the regenerated catalyst to a dryer, wherein the dryer is positioned proximate to the combustion inlet, and contacting the regenerated catalyst with dry air, thereby creating a effluent air stream and a dry catalyst stream; passing the effluent air stream to the regenerator; passing the dry catalyst stream to a stripper; passing a dry inert gas to the stripper to contact the dry catalyst stream, wherein a stripper effluent stream is generated; and passing the stripper effluent stream to the dryer.
