Microwave Reactor for Nitrous Oxide Processing
Journal of Advanced Oxidation Technologies, 2006AbstractThe processing of nitrous oxide in microwave discharge plasma coupled with gliding discharge was investigated. The studies were carried out in a quartz reactor with diameter of microwave discharge space 13 mm or 6mm.

Co-simulation of a reactor assisted by microwaves
2018 International Applied Computational Electromagnetics Society Symposium (ACES), 2018In this paper, the design and analysis of a chemical reactor assisted by microwaves is presented. A co-simulation that links the electromagnetic and thermal phenomena presented in the reactor is performed to obtain the power density and temperature distributions. The results show that a matching network is required to obtain a maximum transfer of power.

Reactions of cyclohexane in a microwave discharge reactor
Journal of Applied Chemistry and Biotechnology, 1972AbstractA study has been made of the reactions of cyclohexane in a continuous‐flow microwave discharge reactor. Butene‐1 and propylene were the major reaction products; ethylene and hydrogen were produced in smaller amounts. The distribution of reaction products was found to depend on the reactor pressure and flow‐rate.

Modeling of microwave reactors : microwave and kinetics in gas flow approaches
Le Journal de Physique IV, 1998The modeling of microwave plasma reactors must couple the external hf field to the kinetics of charged particles and neutral species in presence of a gas flow. Various approaches to solve the non-linear coupled equations which describe the physical situation, are proposed and discussed in this paper.

Characterization of a Microwave Plasma Etching Reactor
2007 IEEE 34th International Conference on Plasma Science (ICOPS), 2007Summary form only given. Plasma-assisted etching is used extensively for device fabrication processes in the semiconductor and MEMS fabrication industries. One variation of low-pressure, high-density plasma-assisted etching machines is the microwave ECR etcher.

Modelling of a microwave postdischarge nitriding reactor
Surface and Coatings Technology, 1993Abstract In a postdischarge nitriding reactor, reactive species, which have a short lifetime, are created by means of a plasma and then sent by convection towards the sample which is to be treated. The aim of the model presented here is to optimize the gas flow characteristics (composition, flow rate, pressure etc.) in order to obtain a maximum ...

Modelling and simulation of microwave plasma reactor
Plasma Devices and Operations, 2004Using the Finite Integration Technique, we have simulated electromagnetic field distributions in the microwave plasma reactor. The relationship between electric field distribution and the length of antenna inserted into the microwave plasma reactor has been simulated. The effect of the length of antenna inserted into the microwave plasma reactor on the
