Method for low temperature plasma dual-electric field assisted treatment of gas containing methane to synthesize compounds

Abstract

The invention provides a method for low temperature plasma dual-electric field assisted treatment of gas containing methane to synthesize compounds. According to the method, two corona discharge electric fields with different electric polarities in a plasma dual-electric field assisted reactor are used for forming dual plasma electric fields, reaction gas is fed into the reactor, and the reactor contains corona discharge dual electric fields; the dual electric fields include a first electric field and a second electric field, the first electric field is a positive corona discharge electric field, or an alternating corona discharge electric field, or other electric field sources that can provide enough energy to oxidize and decompose reaction gas molecules into atoms, ions, free radicals and the like; the second electric field is a negative corona discharge electric field, and organic compounds such as fatty hydrocarbons, high-carbon ethers, high-carbon alcohols, high-carbon esters andlow-carbon alcohols are obtained through reforming and reduction; inorganic compounds such as N2, O2, H2SO4 and NH3 can also be obtained.

Description

technical field [0001] The invention belongs to the technical field of plasma-assisted chemical reactions, and in particular relates to a method for synthesizing organic compounds and inorganic compounds by low-temperature plasma double-electric field-assisted treatment of methane-containing gas. Background technique [0002] Plasma is a gas molecule excited by energy such as heat or an electric field to form an aggregate composed of electrons, ions, atoms, free radicals, and molecules. The number of positive and negative charges in it is basically equal, so it is called plasma. According to the plasma energy state, temperature and ion density, it can be divided into high temperature, hot and cold plasma. In cold plasma, electrons can have kinetic energy above 5eV, and molecules, free radicals, and atoms can be in the range from room temperature to hundreds of degrees. Electrons with sufficient energy can inelastically collide with gas molecules to convert them into active ...
