Title
(EN) PRODUCTION OF NITROGEN OXIDES
(FR) PRODUCTION D'OXYDES D'AZOTE
Abstract
(EN)
A method and apparatus for the manufacture of nitric oxide and/or nitrogen dioxide in which a plasma is formed from nitrogen and oxygen passed through gas inlets into a reaction chamber to create a vorticular flow in the reaction chamber. A source of microwave energy is used to energise the nitrogen and oxygen in a microwave transparent inner plasma containment cylinder to create the plasma.
(FR)
L'invention concerne un procédé et un appareil pour la fabrication d'oxyde nitrique et/ou de dioxyde d'azote dans lesquels un plasma est formé à partir d'azote et d'oxygène qui sont passés à travers des entrées de gaz dans une chambre de réaction afin de créer un écoulement tourbillonnaire dans la chambre de réaction. Une source d'énergie micro-ondes est utilisée pour exciter l'azote et l'oxygène dans un cylindre de confinement de plasma interne transparent aux micro-ondes afin de créer le plasma.
