Title:
GLIDING ARC PLASMA REACTOR, AND METHOD FOR CONVERTING METHANE BY MEANS OF PLASMA
Document Type and Number:
WIPO Patent Application WO/2023/116630
Kind Code:
A1
Abstract:
The present invention relates to the field of energy chemical industry, and disclosed are a gliding arc plasma reactor, and a method for converting methane by means of plasma. The reactor comprises a reactor cavity and a gliding arc plasma generator arranged in the reactor cavity, wherein the gliding arc plasma generator comprises at least two arc surface electrodes which are symmetrically distributed, such that a discharge area can be formed between the arc surface electrodes. According to the gliding arc plasma reactor provided in the present invention, the conversion rate of methane can be significantly improved when methane is converted into olefin; the selectivity of ethylene in the product is improved; and carbon deposition is significantly reduced. In addition, compared with a traditional process for preparing olefin from methane, no CO2 is generated; the ignition and explosion risk is avoided; and the reactor is safer and more environmentally friendly.
