Popis: |
High alumina LTA-type zeolite material, so called zeolite A (Si/Al = 1), is an archetype drying agent (water adsorbent) as well as ion exchanger (e.g. in water softening) [1]. Incorporating more Si in the framework, i.e. increasing Si/Al ratio, renders this kind of materials more (hydro)thermally stable and apt for catalytic application, in particular for vehicle exhaust gases purification [2, 3]. Cu-LTA were found exceptionally active catalysts in NH3-SCR even after hydrothermal aging at 900 °C, the temperature at which the commercial catalyst deforms and loses activity [4]. In the scope of this research challenges of preparing high/all- silica LTA zeolites are going to be addressed. Besides, several examples of their successful preparation will be demonstrated. |
