Energetic Characterization of Faujasite Zeolites Using a Sensor Gas Calorimeter

In addition to the adsorption mechanism, heat released during exothermic influences chemical reactions that follow heterogeneous catalysis. Both steps depend on structure and surface chemistry of catalyst. An example a typical catalyst is faujasite zeolite. For zeolites, influence Si/Al ratio number Na+ Ca2+ cations was therefore investigated in systematic study. A comparison between NaX (Sodium type X faujasite) NaY Y zeolite reveals higher smaller zeolites leads lower loadings heats. The exchange for also has an process. Loadings heats first decrease slightly at low degree increase significantly with calcium contents. If stronger interactions are required catalysis, then CaNaX must have above 53%. energetic contributions show highest-quality sites III III’ make contribution load-dependent adsorption, which about 1.4 times (site III) 1.8 III’) larger than site II.
