Method for converting methane by plasma

Номер: CN116272759A
Принадлежит:

The invention relates to the field of plasmas, and discloses a method for converting methane by using plasmas, which is carried out in a gliding arc plasma reactor comprising a reactor inlet (1), a blade electrode gliding arc generator, a lower reaction zone (4) and a product outlet (5), the blade electrode sliding arc generator comprises a gas nozzle (2), a blade electrode (3) and a base (6); and at least two blade electrodes (3) which are symmetrically distributed are arranged on the base (6). According to the method for converting the methane through the plasma, the conversion rate of the methane can be remarkably increased, the energy consumption can be reduced, the selectivity of ethylene in a product can be remarkably improved, carbon deposition can be remarkably reduced, and compared with a traditional process for preparing the olefin through the methane, CO2 is not generated, the burning and explosion risk is avoided, and the method is safer and more environmentally friendly.
