Embodiment Construction

[0023] The specific implementation of the present invention will be described in detail below in conjunction with the technical scheme and accompanying drawings.

[0024] In the figure, the reaction gas methane and hydrogen are divided into two paths through the mass flow meter and then mixed from the raw material gas inlet 10 into the insulating cylindrical reactor 9. The metal cylinder 11 with the helical metal belt 4 in the reactor passes through the insulating joint 3 and The magnetic fluid sealing device 1 is connected, and then connected to the driving device through the lead-out end 12 of the magnetic fluid sealing device; the other end of the rotating electrode is connected to the metal groove base 8 through a rolling bearing, and high voltage is introduced from the metal groove base extension 7. A circular metal barrel 5 as a fixed electrode is placed at the spiral electrode and kept concentric with it, and the lead-out end 2 of the fixed electrode is connected to the ...

Abstract

An atmospheric glow-discharge plasma reactor with rotary spiral electrode for preparing C2 hydrocarbon from methane features that its rotary spiral electrode is made up by fixing the spiral metallic band with toothed edge to a cylindrical metal column, and the electrically insulated top end of said electrode is linked to sealing unit. Its advantages are high uniformity of plasma distribution and high reaction efficiency.

Description

technical field [0001] The invention belongs to the technical field of plasma discharge reactors, and relates to an atmospheric pressure glow discharge plasma reactor with rotating spiral electrodes. Background technique [0002] Methane is the main component of natural gas and coalbed methane, and it is also one of the main greenhouse gases. With the increasing depletion of oil resources, the rational use and development of natural gas has very important economic benefits and social benefits for environmental protection, future energy utilization and resource allocation. benefit. Due to the high dissociation energy of the C-H bond of methane molecule and its unfavorable reaction in thermodynamics, breakthroughs have not been made in the traditional catalytic coupling of methane. However, low-temperature plasma technology provides a new activation method with its superior reaction conditions. Methane coupling is a high-efficiency green process. [0003] Most of the existin...
