Abstract
The invention is directed to a bypass device for extending the operating life of fixed bed reactors. The device may be placed within a fixed catalyst bed to partition the bed into a first top bed and a second virtual bed. The bypass device allows any fluid feedstock to bypass the first top bed of the fixed catalyst bed as it fouls and enter the second virtual bed under conditions that promote depositing any foulants contained in the bypass flow on the top surface of the second virtual bed rather than in the interstices of the second virtual bed. The invention also relates to an improved fixed bed reactor comprising the inventive bypass device and a method for extending the operating life of a fixed bed reactor that employs the inventive bypass device.
