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 chamber and a gliding arc plasma generator arranged in the reactor chamber, 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 CO 2 is generated; the ignition and explosion risk is avoided; and the reactor is safer and more environmentally friendly.

The invention relates to an integrated system, comprising a system for the electrothermal production of ethyne and a system for power generation, wherein the system for the electrothermal production of ethyne is connected to the system for power generation by way of a line. In the system for power generation, power is generated from a product gas obtained from the system for the electrothermal production of ethyne. Said integrated system allows a flexible use of electricity by way of a method in which the system for the electrothermal production of ethyne is operated in times of high power supply, and at least a part of the hydrogen and/or gaseous hydrocarbons obtained besides ethyne, is stored, and in times of low power supply, stored hydrogen and/or gaseous hydrocarbons are supplied to the system for power generation.

The invention relates to an integrated system, comprising a system for the electrothermal production of ethyne and a separating device for separating ethyne from the reaction mixture of the electrothermal production of ethyne obtaining at least one gas stream containing hydrogen and/or hydrocarbons. The integrated system has a device for introducing a gas into a natural gas grid, to which a gas stream containing hydrogen and/or hydrocarbons is fed from the separating device by way of at least one line. Said integrated system enables a flexible use of electricity by way of a method in which a gas stream containing hydrogen and/or hydrocarbons is fed from the separating device into a natural gas grid, and subject to the power supply, the quantity and/or the composition of the gas stream supplied to the natural gas grid is modified.
摘要:
An ethylene production apparatus for producing ethylene from a methane-containing gas includes a ceramic membrane having at least one of oxide ion conductivity and proton conductivity; a first catalyst layer that is disposed on a first face of the ceramic membrane and includes a catalyst for accelerating oxidative-coupling-of-methane reaction; a methane supply unit that supplies the methane-containing gas to a space located on the same side as the first face of the ceramic membrane; and a charge transfer unit that transfers an electron from the first face to a second face of the ceramic membrane or transfers a hole from the second face to the first face. The ethylene production apparatus produces ethylene in the first catalyst layer upon supply of the methane-containing gas from the methane supply unit.
