A serial plasma cracking flow reactor and its operation method

Abstract

The invention discloses a series plasma pyrolysis flow reactor and an operation method thereof, which comprises a series flow pipe, a dielectric layer, a high-pressure copper plate, a low-pressure copper plate, an upper electrode shell, a lower electrode shell, an electrode connecting ear, a high-pressure electrode and a grounded electrode; the series flow pipe comprises a first-stagepyrolysis device, a second-stagepyrolysis device, an electrode fixing surface, a round pipe, an observation window, a temperature measuring port, a fuel inlet and a product outlet, the first-stagepyrolysis deviceand the second-stagepyrolysis device are arranged in the middle of the series flow pipe with a proper distance. The reactor has a compact structure and reasonable design; the second-stage pyrolysis device can be arranged at the back of the first-stagepyrolysis device to control the airflow velocity to change the residence time of a treated species in the two pyrolysis zones, so that the state of the species which reaches the secondpyrolysis device after first pyrolysis is different. The effects of treatment of stable species and pyrolysis of intermediate species by plasma on final pyrolysis products are studied.

Description

technical field [0001] The invention belongs to the technical field of plasma fuel cracking, and relates to a flow reactor and an operating method thereof, in particular to a serial plasma cracking flow reactor and an operating method thereof. Background technique [0002] When studying plasma cracking fuel oil, in order to reduce the difficulty of research and control a single variable, the gaseous fuel or the vaporized liquid fuel (at normal temperature) is usually diluted and passed into the quartz tube, and it passes through the discharge plasma area. The high-energy particles contained in the plasma (such as electrons and excited state particles) collide with the fuel molecules to generate combustible substances with smaller mass numbers. However, the existing flow reactor usually only contains one plasma generating device, and its research content is single. Usually, the gas flow velocity is changed to study the influence of the residence time of the processed substanc...

AI Technical Summary

Problems solved by technology

However, the existing flow reactor usually only contains one plasma generating device, and its research content is single. Usually, the gas flow velocity is changed to study the influence of the residence time of the processed substance in the plasma region on the plasma cracking product, or the applied voltage and Discharge frequency to study the influence of discharge parameters on plasma cracking products, etc.
