dc.abstract.en A structured reactor was built from stacked catalytic knitted wire gauzes. The cobalt oxide catalyst was deposited on the wire gauze surface using the plasma enhanced metal-organic chemical vapour deposi- tion method. The Raman scattering, electron diffraction and photoelectron emission analyses of the cat- alyst surface evidenced the formation of a cobalt oxide spinel with crystallites of about 5 nm. The results of kinetic studies of VOC combustion (using n -hexane as a probe molecule) performed in a gradientless reactor allowed determining the reaction order and activation energy for this catalytic reaction. It has been proved that reaction follows first order kinetics. Two reactor models (plug-flow and plug-disper- sion) were compared and the simpler plug-flow one is recommended due to the negligible influence of axial dispersion. Experiments were performed in a large laboratory reactor (temperature up to 873 K, gas stream up to 10 m 3 /h STP) for catalytic conversion of VOCs ( n -hexane). The model validation has shown satisfactory accuracy with maximum and average errors of 12% and 4%, respectively. pl
