Spectroscopic Study of an Expanded Argon Microwave (2.45 GHz) Plasma at Atmospheric Pressure in a Helium Environment
(SAGE, 2009)In the present work, an argon microwave (2.45 GHz) plasma flame created at the end of a surface-wave-sustained discharge column in a helium environment has been experimentally studied. This is a plasma with new possibilities ... -
Selectivity Control in a Microwave Surface-Wave Plasma Reactor for Hydrocarbon Conversion
(Wiley, 2011)Drastic changes in the selectivity toward different products have been found in the transformation of n-hexane in a microwave surface-wave plasma reactor. Either ethylene or hydrogen can be obtained with a high selectivity ... -
Measuring the electron density in plasmas from the difference of Lorentzian part of the widths of two Balmer series hydrogen lines
(Elsevier, 2015)We present an alternative optical emission spectroscopy method to measure the plasma electron density from the difference of widths of two Balmer series hydrogen lines (Hα and Hβ), especially convenient for non-thermal ... -
Gas temperature determination in microwave discharges at atmospheric pressure by using different Optical Emission Spectroscopy techniques
(Elsevier, 2013)Non-thermal plasmas sustained at atmospheric pressure are considered as a very promising technology for different purposes, in which the knowledge of the gas temperature is an important issue. In this paper, the gas ... -
Transformation of light paraffins in a microwave-induced plasma-based reactor at reduced pressure
(Elsevier, 2010)In this work, the effects of the plasma chemistry of an argon microwave (2.45 GHz) discharge at reduced pressure on the conversion of three different alkanes (n-pentane, n-hexane and n-heptane) have been studied. Optical ...
