  • Patent number: 11148116
    Abstract: Method and apparatus for synthesizing compounds by a low temperature plasma dual-electric field aided gas phase reaction are provided. The method utilizes two different electrode corona discharge fields in a plasma aided reactor to form a plasma dual-electric field, using electric energy to convert gas into gas molecules, atoms, ions and/or free radicals, and then reforming and reducing to obtain organic compounds such as aliphatic hydrocarbons, higher carbon ethers, higher carbon alcohols, higher carbon esters, lower carbon alcohols, and the like; also inorganic compounds such as N2, O2, H2SO4, NH3, and the like. The apparatus includes a reactor having a plasma region of two different corona discharge fields, wherein an alternating current corona discharge field or a positive corona discharge field is set in the first electric field, and a negative corona discharge field is set in the second electric field.

  • Publication number: 20130043119
    Abstract: Provided are electronegative-ion-aided methods and apparatus to achieve reduction of carbon dioxide gas into useful products. In one embodiment, using different methods of discharge, the electronegative gases forms non-equilibrium electronegative ions, so that carbon dioxide reduction occurs for the production of organic compounds. When carbon dioxide is introduced into the container containing at least one electronegative gas, such as water, ammonia, bromine or iodine vapor, it reacts to form organic compounds, such as ethanol, methanol, and oxalic acid in the case of water, urea in the case of ammonia, and tetraiodomethane in the case of iodine.

  • Patent number: 7896950
    Abstract: Provided are plasma-aided gas storage methods and apparatus. In one embodiment, a porous powder bed assembly equipped with corona discharge electrodes is used to generate a non-equilibrium plasma of negatively ionized gas molecules which absorb onto porous particles, e.g., activated charcoal, to form a gas storage entity. Gas adsorbed onto the particles is desorbed at moderate temperatures by aid of ultraviolet light illumination.
