The selective styrene oxidation for benzaldehyde production under microwave irradiation was studied over Co-ZSM-11 and Fe-ZSM-11catalysts. Their catalytic activity was evaluated by using these catalysts in two different forms: compacted pellets and fine particles. Thus, two reaction systems were studied: batch system with fine particles in suspension and recirculating batch system through a fixed bed system comprising the compact catalyst pellets. The first one presented a higher catalytic activity since the styrene oxidation is able to occur without significant internal diffusional resistance of the reagents towards the active acid sites of the zeolite structure.
