Nonthermal plasma reactors and plasma chemistry
The main goal of this paper is focused in reviewing the last 22 years of the use of nonthermal plasma reactors as alternative technologies for the treatment of residual fluid substances, regarding the destruction of hazardous compounds or the synthesis of other valuable compounds. The electrical discharge processing has emerged as alternative plasma-based technologies. Electrical discharges can ...

Decomposition of benzene by non-thermal plasma processing: Photocatalyst and ozone effect
Plasma technology has some shortcomings, such as higher energy consumption and byproducts produced in the reaction process. However non-thermal plasma associated with catalyst can resolve these problems. Therefore this kind of technology was paied more and more attention to treat waste gas. A hybrid system comprising a non-thermal plasma reactor and nanometer titanium dioxide catalyst was used ...

Influence of streamer-to-glow transition mode on the NO removal by an inductive energy storage type pulse power generator
Influence of streamer-to-glow transition on NO removal from a simulated diesel exhaust gas is described in this paper. A coaxial cylinder nonthermal plasma reactor was driven by an inductive energy storage pulse power generator employing a fast recovery diode as semiconductor opening switch. The NO removal increased with input energy into the reactor. The energy efficiency for 30% NO removal was ...

Pyrolysis processing of used old tyres by thermal plasma technology
Thermal plasma pyrolysis of used old tyres was studied in a nitrogen plasma reactor in order to evaluate the material and energy recycling potential. The main gaseous products from thermal plasma pyrolysis of used old tyres were identified by chromatography as H2, CO, CH4, C2H2, C2H4. In the presence of water steam injection into the plasma reactor, the yield of H2 and CO can reach up to 38.3% of ...

Feasibility of a CHP driven industrial park based on exergy analysis
Industrial zones are manufacturing plants clustered in a given part of a city. Such clustering is primarily dictated by zoning regulations that tend to isolate residential, business, and industrial neighbourhoods. A number of properly matched manufacturing plants can be clustered within a given proximity with a primary objective of optimising their energy use. As secondary goals the cluster may ...

Nano-textured polymer surfaces with controlled wetting and optical properties using plasma processing
Wettability control is of great importance in many applications, from manufacturing of water repellent surfaces to droplet frictionless motion in microfluidics, and biocompatibility tuning. Wetting or repellent behaviour is governed by both surface chemistry and topography. In particular, super-hydrophobicity is attained by combining high-aspect-ratio (HAR) geometrical characteristics with low ...

Characteristics of rotating arc for CF4 removal
Characteristics of CF4 treatment process with a rotating arc are investigated under different thermal and non-thermal plasma conditions. To generate high temperature or non-thermal plasma conditions, a rotating arc reactor is operated with various operating conditions, which are species of carrier gases, flow rates, and input power. Test results reveal that that high temperature conditions caused ...

Time resolved plasma diagnostics for pulsed 2.45 GHz hydrogen discharges
A review of the last ten years of advances in temporal resolved plasma diagnostics for pulsed operated 2.45 GHz microwave-driven hydrogen discharges is presented. Special attention has been paid to the study of breakdown and decay processes where Hiden systems have been used showing relevant results. Density and temperature measurements: Langmuir probe made of tungsten wire 6mmlong and 0.5 mm ...
