Sara Pharm Solutions scientists, together with University „Politehnica” of Bucharest, Faculty of Applied Chemistry and Materials Science, Chemical Engineering Department, managed to study m-xylene catalytic combustion in a laboratory set-up, over a commercial Pt/Alumina catalyst, using concentrations typical for depollution applications. The operating conditions consisted in temperatures within the interval 120-360 oC, hydrocarbon concentration in the range of 450-1300 ppmv and WHSW (volume flow rate to catalyst weight ratio) between 0.067 and 0.2 m3kg-1s-1. In these conditions was observed a negative reaction order in respect with the m-xylene, a total m-xylene combustion being obtained at temperatures above 250 oC. A power law kinetic model was found to adequately correlate the experimental data. More information is available at
