摘要
The article presents investigations of catalytic CuO/gamma - Al2O3 coatings obtained by activated thermo-chemical condensate deposition method. It was researched: a) coating adhesion, resistance to acids, phase and chemical composition, crystal dimensions, morphology; b) technical solutions and main parameters of the test facility for catalysts testing and determining conversion of carbon monoxides and nitrogen oxides; c) catalytic CO and NO, conversion, in comparison of two type catalytic monoliths: CuO/gamma - Al2O3 (on the steel plates, thermally processed at 650 degrees C) and Pt/Mg2Al4Si5O18 (Pt/cardierite, classical ceramic TWC catalyst). The obtained results show that CuO/gamma - Al2O3 type catalyst, has higher inflammation temperature in all cases in comparison with Pt/cardierite type catalyst. CuO/gamma - Al2O3 type catalyst the same as Pt/cardierite type catalyst operates well in case of NOx conversion, if low oxygen amount is present in flue gas. In case of CO conversion, having oxygen concentrations 0.6% and 1.2% at the inlet to catalytic reactor, Pt/cardierite type catalyst reaches 92%, while CuO/gamma - Al2O3 type catalyst maximum available - 100% conversion.
