摘要: The present work highlights the intrinsic catalytic properties of extruded clay honeycomb monolith toward complete oxidation various air pollutants namely CO, methane, propane, acetylene, propene, n-butene, methanol, ethanol, n-propanol, n-butanol, acetone, dimethyl ether, benzene, toluene, o-xylene, monochlorobenzene and 1,2-dichlorobenzene. Total conversion was achieved for all tested compounds with different behaviors depending on pollutants' structural chemical nature. comparison T50 values obtained from light-off curves allowed establishment following reactivity sequence: ketone>alcohol>ether>CO>alkyne>aromatic>alkene>chlorinated aromatic>alkane. performances natural ascribed to implication a quite complex mixture constituted by OH groups (Bronsted acids) coordinately-unsaturated cations, such as Al(3+), Fe(3+) Fe(2+) (Lewis acids). Hence, combination clay's easier extrudability suggests promissory potential application in pollution control.
