Abstract
This invention provides processes, systems and devices for cooling catalyst, preferably regenerated catalyst, by superheating steam and boiling water. The inventive process advantageously provides ideal cooling conditions while ensuring minimal hydrothermal deactivation of the catalyst during the cooling process. The invention is particularly well-suited for cooling catalyst in an oxygenate to olefins reaction system.
