Capture of aerosols by operating catalyst—zark effect

The effect of collecting aerosols by an operating catalyst was found experimentally by filtration of dust-loaded gases through the catalyst bed. It is shown that the efficiency of collecting dust through the filtrating catalyst bed increases sharply during the oxidation reactions of SO 2, NH 3 and CH 4 conversion. Aerosol particles get an impulse of motion at the exothermal reaction. This impulse is directed from the catalyst surface to the center of the gaseous flow. With the growth of the catalyst activity the efficiency of collecting dust and the difference of electrical potential between entrance and outlet sections of the catalyst bed increases. With decreasing dimensions of particles (at the analysed range from 9 to 0.8 μm) the efficiency of collecting dust by the filtrating catalyst bed increases.
