This paper presents the first attempt to investigate of natural zeolite for cooling adsorption application. Representative samples were collected from Bayah-Banten, Indonesia. As known that zeolites can be used as an adsorbent. Unfortunately, natural zeolite has many limitation, among them contains a lot of impurities. To improve the characteristic of natural zeolite, activation and modification should be conducted beforehand. Activation was conducted by reducing grain size (1-2mm), washed by aquadest and heated using microwave. While the chemical activation is done through acidification by adding HCl solution. Finally, the activated natural zeolite was calcined gradually initiated at room temperature to 150°C for 2 hours and then heating continued from 150°C to 300°C for 4 hours. The final zeolite activated product was characterized by X-Ray Diffraction (XRD), Brunauer-Emmett-Teller (BET) and Transmission Electron Microscopy (TEM). The result showed that the morphology of the natural zeolte was cubic shave as observed by TEM and the surface area of activated natural zeolite is geater than the raw material.
