Résumé
The development of economic and environmental process for the synthesis of multifaceted functional zeolitic material received considerable attention. In this study, zeolite type faujasite was prepared from glass waste and aluminum scraps recovered from municipal solid wastes. The prepared zeolite was tested in the selective catalytic reduction of NO with NH3 using simulated diesel exhaust consisted of NO 1000 ppm, NH3 1000 ppm in presence of oxygen (8%) and water vapor (3.5%). The alkaline fusion prior to hydrothermal synthesis technique was used for the preparation of the zeolite. XRD and SEM techniques showed that the main product after hydrothermal treatment at 60 °C for 6 days is the zeolite type faujasite contaminated with small quantity of zeolite Na-P1. The ammonium form of the prepared zeolite and copper acetate precursor were used to prepare a series of three catalysts having different copper loadings (5%, 7% and 10%). Cu(10)-Z1 catalyst showed excellent NO conversion reaching 98 % in large temperature window 180 °C to 550 °C.
