Abstract
Abstract A method for cleaning an exhaust gas, comprising bringing the exhaust gas into contact with a crystalline aluminosilicate having a primary particle size of not less than 0.5 micron, containing ions of at least one metal of Group Ib and/or Group VIII of the periodic table in an amount ranging from 0.2 to 0.8 equivalent relative to one gram atom of aluminum, and having a mole ratio of SiO2/Al2O3 of not less than 20.
