COMBUSTION OF VOLATILE ORGANIC-COMPOUNDS OVER MONOLITHIC CATALYSTS

The Research Group of Ecological Catalysis, Technical University of Wroclaw, concentrates on the preparation of monolithic catalyst on metal foil supports (A1-Ti or steel). Five noble metal catalysts, platinum and palladium (and two of them with Rh ingredient), were prepared for the laboratory tests. They were tested for combustion of four different species - toluene, n-heptane, acetone and ethanol. The results of laboratory tests were of utility in the preparation of the catalythic monolith for a lacquer drier (SEM 300). Activity tests were carried out under normal conditions of drier operation and they corroborated the expected high activity of the catalyst. The compact unit (drier and catalyst) allowed also for energy savings during the whole drying cycle. High activity of the monolithic catalyst in this process allows us to assume that it will be applicable to the combustion of other organic polluting species, replacing traditional granular catalysts.
