The Adsorption – desorption is considered as one of the most promising VOCs treatment technologies due to its cheap operational cost and low energy consumption. However, there are a huge amount of adsorbed VOCs released in desorption process. That is the reason why this study focused on the combination of adsorption-desorption with catalytic oxidation to treat completely VOCs as toluene. The adsorption catalyst MnCoCe/AC (metal oxide catalyst MnO2-Co3O4-CeO3 on Actived carbon) and oxidation catalyst Au/MnCoCe (Au supported on metal oxide catalyst MnO2-Co3O4-CeO3) were investigated and characterized by SEM - EDX, BET. The catalytic activity test were carried out on a micro-flow reactor system connected with GC online using a TCD detector.The results shown that Au/MnCoCe is a potential catalyst for the complete oxidation of toluene with the temperature for 100% toluene conversion of 300oC. The combination of adsorption-desorption with catalytic oxidation decreased the temperature for 100% toluene conversion to 250 oC.
