The effect of silica packing in an ozone generator fed with oxygen-nitrogen mixtures has been studied. measurements were carried out a double-sided cooled discharge gap, which placed. In the presence considerably higher concentrations achieved than without packing. An especially clear was observed air-fed conditions. It found that increase concentration obtained coincides N2O post-reaction gas.
The results of studies on the ozone synthesis under discharges generated surface ceramic actuator built as concentric-strip electrode system are presented. Experiments were carried out in pure oxygen. ozonizer, which gas flows with variable linear velocity, was used. concentrations and process energy efficiencies show possibility effective generation reactors nonconventionally organized discharge space.
The method of measuring the technical rate ozone synthesis process, and manner utilizing process for determining boundary contents in reacting system has been presented. On basis macroscopic analysis reason causing obtaining concentration lower than that theoretically possible, pointed out. It is shown an increase temperature discharge gap does not inhibit ozone-forming rate. decrease observed a result intensive decomposition. However, under typical conditions decomposition microdischarge...
Changes of the gas temperature in a single microdischarge channel and inside entire discharge gap dielectric barrier were analyzed. It was shown that initial is tens degrees higher than average gap. The expanding effect which causes mixing reaction space presented. has been explained why part ozone decomposed.
Results of studies on ozone synthesis under discharges proceeding in a metal mesh-ceramic dielectric system have been presented. The experiments were carried out the reactor with unique reaction space geometry, which reacting gas flew consequently increasing linear velocity. high voltage electrode was made mesh, caused intensification mixing space. Using simple one-side cooling space, maximum concentrations (100 g/Nm3) and energy efficiencies (180–200 g/kWh) obtained at 25 °C.
The process of ozone production in pure oxygen was studied. It shown how the concentration changes along discharge gap, both during its generation and decomposition processes. effect inlet concentration, power, gas residence time on analyzed. has been that concentrated is easily decomposed at very low powers, i.e., when increase average temperature gap negligibly small. hypothesized most intense takes place microdischarge channels, because heating begins inside them.
The analysis of measurements ozone synthesis process rate in pure oxygen with the use unique plasma reactor was presented. kinetic have been made using integral and differential method. effect energy stream delivered (i.e., power) gas residence time a discharge gap on efficiency carried out dielectric barrier shown. It presented how change along way they depend both power density time.
Dielectric barrier discharges are commonly used for ozone synthesis. The main reactions of this process proceed in the microdischarge channels which variable temperature occurs. discharge gap was modeled. dynamics a gas inside changes were presented.
The estimation of pulsed-spark-discharge efficiency for destroying unwanted stable gaseous impurities is an object the present study. A laboratory-scale reactor was developed to study pulsed spark discharges (PSDs) <formula formulatype="inline" xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink"><tex Notation="TeX">$\hbox{CCl}_{4}$</tex></formula> decomposition under oxidative and nonoxidative conditions at atmospheric pressure.
