英文摘要: ZSM-5 coatings have been synthesized onto a monolithic cordierite substrate by an environmental friendly and high coating selectivity method-Vapor Phase Transport (VPT), With this method, an aluminosilicate gel coated onto the monolithic cordierite substrate has been transformed into a ZSM-5 layer under vapors of n-butylamine and water. n-Butylamine played a key role in the forming of ZSM-5 Layer on the cordierite substrate. The ZSM-5/cordierite monolith composites prepared by this method were ion-exchanged with Cu(2+) and tested for the selective catalytic reduction of NO by propane. The deNO(x) activities of Cu/ZSM-5 monolith catalysts were not only dependent on the ion-exchange methods, but also on the ZSM-5 loading of the monolith catalysts. The best result was obtained over the Cu (B3)/ZSM-5 monolith catalyst, which had a ZSM-5 loading of about 13% and was prepared by a pressure exchange procedure. At a temperature of 723 ii and a space velocity of 10, 000 h(-1) (based on the monolith volume), 85% of NO conversion and 93% of C(3)H(8) conversion were achieved over the Cu(B3)/ZSM-5 monolith catalyst.
