zanieczyszczenie powietrza - Opis:
- The aim of the study was to compare the activity and selectivityof metal oxide catalysts on monolithic or granular supports in the oxidation of toluene and three oxyderivatives-acetone,ethyl acetate and butyl acetate.Four catalysts were manufactured for the purpose of the study-two with perovskite and two with Cu-Zn oxides as active phases,on a cordierite support in the from of a monolith or irregular grains.The shape of the catalyst support did not affect catalytic activity,but it hod an influence on the reaction selectivity in the oxidation of the oxyderivatives.In the presence of Cu-Zn catalysts,more products of incomplete oxidation were obtained for the monolithicshape,and thier concentrations were higher than those for the granular catalyst.For perovskite catalysts an inverse relation was observed.With such discreancy between the results it is impossible to make and generalization on the contribution of the support shape to the selectivity of the catalyst.
