Nitrous oxide is a dangerous environmental pollutant because
it contributes to the destruction of stratospheric ozone
being at the same time a greenhouse gas. The concentration
of N2O in the atmosphere continues to increase (0.2–0.3%
yearly) and this increase appears to be caused mainly by anthropogenic
activities [1,2]. Chemical processes associated
with the production and use of nitric acid and fluidized bed
combustion are the two main nitrous oxide sources, and their
contribution to the total nitrous oxide emissions amounts to
about 20% [3].
