Method for low temperature plasma dual-electric field assisted treatment of gas containing carbon dioxide and/or carbon monoxide to synthesize compounds

Abstract

The invention provides a method for low temperature plasma dual-electric field assisted treatment of gas containing carbon dioxide and/or carbon monoxide to synthesize compounds. According to the method, two corona discharge electric fields with different electric polarities in a plasma assisted reactor are used for forming plasma dual electric fields, reaction gas is fed into the reactor, and thereactor 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 and low-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 gases containing carbon dioxide and / or carbon monoxide. Background technique [0002] Water gas refers to the gas generated by water vapor passing through hot coke. The main components are carbon monoxide and hydrogen. Its composition is roughly: CO 2 5%, H 2 50%, CO 40%, N 2 5%; water and carbon dioxide can be emitted after combustion. Its combustion speed is 7.5 times that of gasoline, and it has good anti-knock performance. According to foreign research and patent reports, the compression ratio can reach 12.5, the thermal efficiency is increased by 20-40%, the power is increased by 15%, the fuel consumption is reduced by 30%, and the exhaust gas purification is close to Euro IV. Standard, can also be...
