Abstract

In this research, the kinetics of oxidation process of carbon-monoxide on the nano-catalyst surface has been investigated. The investigation conducted in different flow conditions and temperature, by the range of T=70-350oC, dependence on kinetic  convertation of carbon monoxide to carbon dioxide in the closed system. Ä°t is determined that speed of conversion process increases by 1.30-1.32 times as temperature increases on the surface of catalyst. At low flow rates the conversion of carbon-monooxide to carbon –dioxide runs more rapidly.

The kinetics dependent  on conversion of mix air, CO to CO2 has been shown on the surface of Nano-Al2O3+CuO  catalyst in different flows and under 70 to 200oC degrees temperatures. It has been determined that at all temperature  ranges, conversion proceeds over 90%. As a result of investigation it is known that conversion speed increases by 1.30-1.32 times, if the temperature is 70-200º C over reactor. Meanwhile, the volume of converted CO increases by 12-14%. Kinetics dependant on conversion of mix air and CO to CO2 has been shown on the surface of  catalyst in different flows and under 300oC degree temperatures. It has been determined that CO to CO2 conversion happens more rapidly in low flow rates rather than high.

At the same time, meeting time on catalyst surface also effects speed of conversion. It is shown at figure 5 that during 15 minutes the conversion at V=38 litr./min volume  carbon monoxide to carbon dioxide (N/No)*100%=50% while  at V=20 litr./min (N/No)*100% volume to be. The increase of conversion at T=300oC-temperature is cause to increase at  (N/No) 87-50=37% while the oxidation processes is occur much speed while confirmation is active in high temperature.
