NOx Production via an Atmospheric Microwave Air Plasma Torch

Abstract

In order to achieve climate neutrality, preferably accompanied by cost reduction, plasmochemical processes open up attractive alternatives for the currently very energy-intensive production of fertilizers. They can be cheaper, more environmentally friendly and agiler than the current state-of-the-art for fixation of nitrogen building blocks. NO_x can be obtained from atmospheric nitrogen in an air-powered plasma torch operating in-loco and on-demand, currently yielding a maximum NO_x concentration of 2.8 %. The torch can be further improved in efficiency and is designed for an easy upscaling.
