Abstract
Reduced thermal overstressing and cracking in the cone of a high efficiency regenerator for fluidized catalytic cracking catalyst is achieved by providing a cylindrical skirt at the base of the cone. The skirt defines an annular space which allows for expansion of the cone during changes in temperature of the regenerator. A catalytic cracking process using the regenerator is also disclosed.
