Calcium exchanged A type zeolite is extensively used as an adsorbent in petroleum and gas
purification application. The precursor of calcium and silver-exchanged zeolite was
prepared in a hydrothermal process, followed by an exchange process. In this study, LTA
zeolite was synthesized. Calcium-ex-changed and silver-exchanged molecular sieves were
prepared and characterized by a series of techniques, such as scanning electron
microscopy, X-ray diffraction, X-ray photoelectron spectroscopy, etc. Physical properties of …
