A non-thermal plasma reactor and method provides individually retained reactor plates. The method comprises stacking an alternating sequence of positive and negative reactor plates to form a reactor stack, placing temporary spacers between the positive and negative reactor plates. In one embodiment, individually retained reactor plates are secured by folds of a ceramic insulating layer extending between plate pairs, with reactor plates secured by the stack retention material and the folds of the ceramic insulting layer. In a second embodiment, individually retained reactor plates are secured with a permanent pleated insulting mica separator disposed on each side of the reactor. In a third embodiment, a retention material extends slightly into the exhaust gas passage at each side of the stack supplying permanent support for the stacked plates.
摘要:
A plasma-based fuel reformer in which a fuel/air mixture is subjected to an electrical plasma arc that reforms the fuel/air mixture into a hydrogen-rich gas. The reformer includes a first electrode defining a reaction chamber and a second electrode axially aligned with the longitudinal axis of the first electrode. A plasma arc forms between the first and the second electrodes in the reaction chamber when an electrical voltage is applied. An insulator is positioned between the first and the second electrode to prevent the formation of a plasma arc between the first and the second electrodes except in the reaction chamber. Means for providing a fuel/air mixture to the reaction chamber and means for diverting the air flow into the reaction chamber so as to create a vortex-like flow of air in the reaction chamber are also included.

This invention relates to the enhancement of chemical reactions by applying a high frequency electric field to a material. The frequency and amplitude of the electric field are selected in accordance with the properties of the reacting components in the bulk of chemical reactor. In general, the high frequency range is determined by the dielectric properties of reactant(s), that is, at any given temperature, when, for example, the specific conductivity starts to grow from its low frequency value. Typically, frequencies in the range of 100 kHz to 200 MHz or greater are suitable for the enhancement of the reactions. An electric field of any shape having Fourier components that when applied to a chemical process exhibits growth in the real part of conductivity relative to the low frequency value is of particular importance.

The plastic film electrostatic adsorption apparatus of the present invention comprises an electrostatic adsorption electrode, an insulated dielectric layer that covers the electrostatic adsorption electrode and has a center line average roughness of an adsorption surface on which a plastic film is placed of 0.5 micrometers or less, and a power supply electrode that applies a voltage to the electrostatic adsorption electrode. According to this plastic film electrostatic adsorption apparatus, surface treatment can be performed even in a vacuum without requiring tedious work such as application or removal of adhesive. In addition, even if the plastic film expands and deforms due to heat treatment and plasma treatment performed during surface treatment, there is no occurrence of wrinkling, deformation or separation in the plastic film due to the difference in thermal expansion between the electrostatic adsorption surface and plastic film.

The present invention is a method and apparatus for altering a carbon-containing compound in an aqueous mixture. According to a first aspect of the present invention, it has been discovered that for an aqueous mixture having a carbon containing compound with an ozone reaction rate less than the ozone reaction rate of pentachlorophenol, use of corona discharge in a low or non-oxidizing atmosphere increases the rate of destruction of the carbon containing compound compared to corona discharge an oxidizing atmosphere. For an aqueous mixture containing pentachlorphenol, there was essentially no difference in destruction between atmospheres. According to a second aspect of the present invention, it has been further discovered that an aqueous mixture having a carbon-containing compound in the presence of a catalyst and oxygen resulted in an increased destruction rate of the carbon containing compound compared to no catalyst.
摘要:
An electro-kinetic electro-static air conditioner includes a self-contained ion generator that provides electro-kinetically moved air with ions and safe amounts of ozone. The ion generator includes a high voltage pulse generator whose output pulses are coupled between first and second electrode arrays. Preferably the first array comprises one or more wire electrodes spaced staggeringly apart from a second array comprising hollow “U”-shaped electrodes. Preferably a ratio between effective area of an electrode in the second array compared to effective area of an electrode in the first array exceeds about 15:1 and preferably is about 20:1. An electric field produced by the high voltage pulses between the arrays produces an electrostatic flow of ionized air containing safe amounts of ozone. A bias electrode, electrically coupled to the second array electrodes, affects net polarity of ions generated. The outflow of ionized air and ozone is thus conditioned.

A non-thermal plasma (NTP) reactor structural conductor element includes a base conductor support and a high dielectric constant (“high k”) barrier layer supported by and substantially surrounding the base conductor support to form a structural conductor NTP reactor element. The structural conductor element may comprise a variety of shapes such as plates, sheets, half-box, I shapes, C shapes, or comb shapes, among others. In one embodiment, the dielectric barrier layer includes a coating applied to the base conductor support. In another embodiment, the dielectric barrier layer includes a high k film laminated to the base conductor support. In yet another embodiment, the base conductor support integrally forms the dielectric barrier layer via conversion of surfaces of the base conductor using electrochemical, thermal or chemical means to form the dielectric barrier layer.
