ABSTRACT:
This invention is directed to controlling regenerator temperature in an oxygenate to olefin process. Because a significant amount of heat can produced in the regenerator during the regeneration process, at least a portion of the heat must be removed to keep the system from getting too hot. This invention removes heat during the regeneration of the catalyst, using appropriate circulation of catalyst between the reactor and the regenerator. Sufficient circulation can eliminate the need for the use of a catalyst cooler in the regeneration system.
