Characterization of Natural Zeolite Synthesized by Dealumination and Desilication Method

Delamination and desilication are two methods used in the hierarchical synthesis of zeolites. This process is important for industrial applications, particularly in synthesizing natural zeolites due to their abundance. For instance, Lampung, Indonesia, has abundant natural zeolites. The synthesis process of natural zeolite can be simplified using the solvent swelling mechanism. The swelling solvent mechanism combines the dealumination and desilication methods into one process, making it advantageous to use natural zeolites as raw materials for manufacturing hierarchical zeolites on an industrial scale. The sample used in this study was Natural Zeolite Lampung (NZL), and the resulting product was characterized as NZL Swelling. In this study, only two characterization analyses were selected to test the reliability of the dealumination and desilication methods simultaneously in one process, namely XRD and BET.
