ZSM-5 zeolites modified by conventional and solid-state ion-exchange were characterized by X-ray diffraction, BET measurements, derivatography, IR spectroscopy in the framework vibration range and acidity measurements with pyridine as probe. NO adsorption and transformation on Cu-, Co-, Ni- and FeZSM-5 zeolites were followed by IR spectroscopy. Mono- and dinitrosyl surface species, adsorbed NjO and NO were detected in different concentrations on the tested catalysts. Differences in adsorption behaviour were observed for samples exchanged by the conventional and solid-state procedures. [Pg.665]

Because the thermal analysis can track the changes of heat, mass and state in the process of preparation and reaction of catalyst, it achieves many applications, not only in the analysis of raw materials, but also in the analysis of process of preparation and usage of catalysts to provide valuable information. " The Thermal analysis has about 20 kinds of different technologies (Fig. 7.21), wherein thermo-gravimetric analysis (TG), derivatography analysis (DTA) and differential scanning calorimetry (DSC) etc are most widely used in catalyst study. [Pg.605]
