Fixed Bed Reactor - an overview | ScienceDirect Topics

Several researchers have chosen to use the fixed bed reactor for the pyrolysis of plastics [44,71–73]. In certain cases, the fixed bed reactor is used after the first noncatalytic stage of pyrolysis has been completed. This is so the gaseous and liquid products from the first stage can be fed into the fixed bed reactor with more ease [25].
