This fact isrealized in aerosol nanocatalysis technology at frequency <strong>of</strong> catalytic system <strong>the</strong> 2-6 Hz.These fluctuations <strong>of</strong> reactor multiply to <strong>the</strong> number <strong>of</strong> dispersive material by <strong>the</strong> particlesimpacts with one ano<strong>the</strong>r.Thus, aerosol nanocatalysis technology is a unique technology that could be used <strong>the</strong>nanoparticles <strong>of</strong> catalyst in a free state. So, <strong>the</strong>ir catalytic activity is increased.References1. A.P. Weber, M. Seipenbusch.
