Abstract
A defined catalyst withdrawal and replacement program for optimizing the productivity and the economics of catalyst consumption in a multi-reactor system is disclosed. Catalyst cost is reduced by minimizing removal of the newest catalyst and maximizing removal of older catalyst to achieve an overall reduction of catalyst age in the multi-reactor system.
