Bliznjuk O. Catalytical processes in technology of nitrogen oxides and nitric acid

Object: catalytic processes of ammonia oxidation by air and oxygen. Aim of study: development of scientific background of catalytic technology for ammonia oxidation to NO and N2O, improvement of technology of HNO3, creation of new generation of catalysts and their technologies. Methods: IR-spectroscopy, x-phase analysis, thermoanalysis, thermodesorption, epitaxy decoration. Results: the physico-chemical features of catalytic processes of ammonia oxidation and nitrogen oxide reduction was considered, the kinetic and technological features of their action under pressure was established, which was the scientific basis for development of the new generation of catalysts and their technologies, for validation of optimal technological regimes and reactors for their realization, for development of new process of catalytic ammonia oxidation to nitrogen oxide, and allowed to solve the important applied problem of intensification of technologies of nitrogen oxides and nitric acid. New: the new scientific fundamentals were proposed and the principles of energy- and resource conservable catalytic technologies in nitrogen oxide and nitric acid technology were validated. Implementation: the design of ammonia oxidation reactor with new catalytic element shape was implemented in aggregates UKL-7 at "Azot" Ltd. (Chrekassy). Application: The results are important for chemical industry of Ukraine.
