EFFECT OF CERTAIN CATALYTIC POISONS ON THE ACTIVITY OF CUPRUM-PALADIUM COMPLEXES APPLIED ON CARBON MATERIAL IN THE REACTION IN THE REACTION OF CARBON MONOXIDE OXIDATION BY AIR OXYGEN

Oxide and metal complex catalysts for low temperature gas-phase oxidation of carbon monoxide by air oxygen lose their activity under the action chemical poisons such as SO2, H2S, PH3, H2O. We have developed a highly efficient Wacker-type catalyst in which carrier is fiber material (CFM), precursor was cellulose hydrate. For catalyst, there are no studies on effect catalytic poisons, namely SO2 H2O, its reaction low-temperature CO with oxygen. The morphology, elemental composition adsorption properties investigated. Pd(II)-Cu(II)/CFM relative to water vapor sulfur dioxide, well protective catalyst. SEM (scanning electron microscope) confirmed morphology typical CFM found very small agglomerates case formed paratacamite Cu2(OH)3Cl crystallites caused surface palladium (II). When applying components, fibers do not shape, but unevenly covered impurities. Palladium (II) reduced about 10%, [Pdo]n observed, while erosion increases surface, phase crystallites. Carbon generally characterized high content oxygen, distribution heterogeneous. In analysis isotherms, classified type IV, it that based belong microporous samples. It proved only at humidity gas-air mixture, equal 30% C < MPCSO2 (20 mg/m3). Catalyst poisoning does disrupt process, increasing amount absorbed dioxide (QSO2 ) degree conversion decreases especially sharply absorption 10.3⋅10–4 mol SO2. Thus, results obtained adsorbed indicate significant reduction monoxide. Therefore, example respiratory protection against CO, preliminary stage moisture should be provided.
