Thank you. I just took a look; that’s how I understand it. A \"stuck bed\" is a special type of operation, while a \"dead bed\" is a certain state. Is that correct?
The bed is sealed to enable diesel to be ignited upon resuming operation, thereby rapidly raising the temperature of the regenerator. A dead bed is an accident condition that occurs during operation.
Dead bed is a handling method in case of accidents, while stagnant bed is a condition that arises when fluidization is poor; in MTO, dead bed areas are incorporated into the design of the reactor bottom from the start
A stuck bed is a handling method in case of an accident, while a dead bed is an operational accident.
Why design a dead bed area? What is the size of a dead bed design?
