PP-III-82REACTOR FOR CO OXIDATION EXPERIMENTS ONHETEROGENAZED CATALYSTS ON THE BASIS OF FIBROUSCARBON MATERIALSKhaminets S.G., Radkevich V.Z., Potapova L.L., Senko T.L., Yegiazarov Y.G.Institute of Physical-Organic Chemistry of the National Academy of Sciences ofBelarus, 13, Surganov St., Minsk 220072, BelarusE-mail: yegiazarov@ifoch.bas-net.byradkevich_vz@ifoch.bas-net.byAir purification from carbon monoxide pollution for respiratory organs protection inextreme situations is very important problem. The most effective method for COremoval from air is catalytic oxidation, that’s why many research works over lastdecades were dedicated to development of the novel catalysts for carbon monoxideoxidation.Active heterogenized CO oxidation catalysts on the basis of fibrous carbonmaterials, manufactured at “Khimvolokno” ent. Svetlogorsk (Belarus), weresynthesized in our laboratory. Catalysts were prepared by means of impregnationfibrous carbon plates (mean diameter 7,8 and 5,0 cm, fibrous carbon materialcarbopon) with acidified aqueous solution of palladium (II), copper (II) and iron (III)salts followed by drying and thermal activation.First type of reactor – model of respirator – was made on the basis of shell(volume for catalyst loading 100 cm 3 , diameter 7,8 cm) from respirator RU-60M filtercell, manufactured by OOO “Briz-Kama” Vladimir (RU). Empty shell was loaded with25 plates of fibrous carbon impregnated with salts solution to achieve maximumpacking density. Then prepared filter cell was griped between flanges of two conicalparts made of caprolon (Pic. 1).Results of catalytic experiments on the model of respirator are shown at Table.Conversion of carbon monoxide at volume velocity of reaction mixture 9000 h –1(0,03% of CO in air) is 94%. Full conversion of CO wasn’t reached due to theleakages of carbon monoxide between catalyst and shell was concluded.Thereupon second type of catalytic reactor was designed and created. Thisreactor contain ring gasket between flanges of upper and lower parts, whicheliminate leakages of reaction mixture past catalyst.594
