Therefore, the inventor provides a fixed bed reactor for realizing efficient methane conversion through research. Through the setting of a cleaning component, the internal filling of the fixed bed reactor is discharged, and the user does not need to use external disassembly and lifting tools to disassemble the fixed bed reactor and take the internal filling, which saves time and effort and reduces the user's workload.
