Abstract
The introduction of the method of chemical trapping of nitrogen oxides in a complex with selective catalytic purification of tail gases from industrial production makes it possible to increase the service life of the catalyst regardless of the NOx concentration, create a cycle of low-waste technology and achieve significant savings in the consumption of the scarce AVK-10 catalyst ... Reuse of the spent catalyst AVK-10 in the process of cleaning tail gases of industrial production from NOx and absorption-catalytic cleaning of the latter with the use of solid waste products allows simultaneously solving environmental and economic problems in the production of weak nitric acid.
