摘要： This invention is to a circulating fluid bed reactor that is designed so as to have the ability to adjust catalyst holdup within the reaction zone of the reactor while maintaining substantially constant catalyst circulation rate through the reaction zone. The ability to adjust catalyst hold up independently of catalyst circulation rate provides an advantage of having the ability to maintain a constant conversion level as catalyst activity or feed rates change.
