чччч The aluminum vanadium catalyst is designed for the process of selective purification of waste gases from nitrogen oxides in the production of nitric acid. The catalyst is vanadium oxide deposited on the surface of active aluminum oxide. It is available in the form of spherical granules, which make it possible to create a uniform compacted loading, improving the processes of heat and mass transfer in the reactor, providing increased cleaning efficiency. It can be produced in the form of cylindrical extrudates.The AVK-10 M catalyst uses additional manganese oxide promotion.
