Химическая коррозия каталитических материалов в системе очистки отработавших газов судовых энергетических установок

Abstract

Object and purpose of research. This paper discusses exhaust gases of marine power plants. The purpose of this study was to investigate acid-mix corrosion of porous permeable catalysts in exhaust scrubbers. Materials and methods. Specially developed program of tests intended to analyse the effect of acid mix upon catalyst in marine exhaust scrubber, as well as the studies on sulfur-nitrogen acid mix upon corrosion behavior of porous permeable catalysts. Main results. The study yielded the data on acid-mix effect upon porous permeable catalysts used in marine exhaust scrubbers. Conclusion. The results of these tests made it possible to estimate how much the catalysts used in marine scrubbing systems are affected by their aggressive environments, as well as to suggest tailor-made compositions of catalytic materials so as to meet the requirements to exhaust cleaning quality.
