PLASMA-ASSISTED METHOD AND SYSTEM FOR TREATING RAW SYNGAS COMPRISING TARS
The invention provides a system and method for conversion of raw syngas and tars into refined syngas, while optionally minimizing the parasitic losses of the process and maximizing the usable energy density of the product syngas. The system includes a reactor including a refining chamber for refining syngas comprising one or more inlets configured to promote at least two flow zones: a central zone where syngas and air/process additives flow in a swirling pattern for mixing and combustion in the high temperature central zone; at least one peripheral zone within the reactor which forms a boundary layer of a buffering flow along the reactor walls, (b) plasma torches that inject plasma into the central zone, and (c) air injection patterns that create a recirculation zone to promotes mixing between the high temperature products at the core reaction zone of the vessel and the buffering layer, wherein in the central zone, syngas and air/process additives mixture are ignited in close proximity to the plasma arc, coming into contact with each other, concurrently, at the entrance to the reaction chamber and method of using the system.

Device for disinfectant agent application and generation and method of use
A device for obtaining and applying a disinfectant agent and method of use are provided. The device includes a pre-processing cascade unit that activates (ionizes) air, with the activated air being supplied by an air pump to an inlet of a sprayer, where the activated air mixes with an initial working fluid (distilled water) to form an activated air-working fluid aerosol mixture that is sprayed by the sprayer into a reactor of cone-shaped volumetric cold plasma that includes divergent discharge electrodes. The device further includes a unit for generating high-voltage pulses of a nanosecond duration that is connected to the discharge electrodes and that causes the electrodes to generate electrical discharges. Upon the mixture coming into contact with the electrical discharges, potent disinfectant agents (such as peroxynitrite and one or more peroxynitrite's precursors or derivatives) are synthesized and expelled from the device.
METHOD AND APPARATUS FOR SYNTHESIZING METHANE GAS FROM CARBON DIOXIDE AND HYDROGEN AT ROOM TEMPERATURE AND ATMOSPHERIC PRESSURE
A methane (CH.sub.4) gas is synthesized from carbon dioxide (CO.sub.2) and hydrogen (H.sub.2) using catalyst-dielectric barrier discharge (DBD) plasma at room temperature and atmospheric pressure. In the method and apparatus for synthesizing methane gas of the invention, methane (CH.sub.4) gas, which is synthetic natural gas, can be effectively synthesized only from carbon dioxide (CO.sub.2) and hydrogen (H.sub.2) using DBD plasma at room temperature and atmospheric pressure, and also, additional heating and pressurization devices are not used during the methane gas synthesis process, thus reducing production costs and realizing high-value-added processing due to the absence of risks during the processing.

Method and Apparatus for the Industrial Production of New Hydrogen-Rich Fuels
A method for bonding a fluid to a substance includes filling a first pressure vessel with the fluid and pressurizing the first pressure vessel to a first pressure. The fluid is the circulated through an electric arc formed within the first pressure vessel, thereby creating a treated fluid. Within a second pressure vessel, the substance is exposed to a magnetic field, thereby forming a polarized substance. The treated fluid and polarized substance are combined under a second pressure within a third pressure vessel, thereby exposing the treated fluid to the polarized substance at a pressure sufficient to achieve a bond.
