Catalytic Abatement of Toluene from Waste Gas Streams over Nanostructured Ceria, Activated Clinoptilolite and Alumina

The aim of this work is to study combustion of toluene (1000 ppm) over different supports of nanostructuredceria, activated clinoptilolite and alumina. Natural clinoptilolite were obtained from west regions of Iran and modifiedby ion-exchange (1 M NH4NO3) and acid leaching using 1 M HCl. Catalysts characterised by XRD, BET, EDX andFESEM. Ion-exchange with NH4+of natural zeolites results in the exchange of the cations. Acidic treatments causesignificant dealumination and decationisation, as well as losing of crystalline, increase significant surface area and theformation of amorphous material. The reactor performance shown that catalytic activity of the treated clinoptiloliteimproved and close to catalytic activity of alumina.
