Synthesis of Zeolite from Geothermal Waste

Abstract:

Article Preview

The high content of silica in geothermal waste can be used as a alternative source of amorphous silica for the production of silicon based materials. In this research, geothermal waste was used as silica sources in hydrothermal reaction of zeolite synthesis. Zeolite was synthesized by unstirred hydrothermal process. Hydrothermal process was conducted at variation temperature 100, 110 and 120 °C for 5 hours. To study the effect of holding time on hydrothermal product, hydrothermal process also done in variation of: 1, 3 and 5 hours holding time at temperature 120 °C. All of hydrothermal products were characterized by XRD. The results show hydrothermal process successfully converts geothermal waste into zeolite A and sodalite.
