Abstract
A new type of contactor is proposed for the combustion of Volatile Org anic Compounds (VOCs) in diluted streams. This is based on the use of Pt/gamma-Al2O3 catalytic ceramic membranes operating in the Knudsen di ffusion regime, which gives a highly efficient contact between the rea ctant feedstream and the catalytic material on the membrane. Essential ly, complete combustion of toluene (used as an example of VOCs) in the range 100 to 5100 ppm was achieved at temperatures between 150 and 20 6 degrees C, using superficial velocities between 3 and 7.5 m/h.
