ABSTRACT:
Operational flexibility of a fluid catalytic cracking process is improved by indirectly cooling catalyst in an endothermic catalyst cooler. Catalyst withdrawn from the FCC unit is cooled by driving an endothermic chemical reaction, which may be either thermal or catalytic. Dehydrogenation of, e.g., light aliphatics, produced by the cracking reactor in the endothermic cooler allows the FCC unit to adapt to heavier feeds. A preferred endothermic cooler, comprising a base heat exchanger section, transport riser, and solids collection and recycle vessel is disclosed.
