Synthesis of Na-P Zeolite from Geothermal Sludge

摘要

Geothermal waste from PT. Geo Dipa Energy Dieng was transformed to Na-P zeolite (CFA-ZP) experimentally at a low temperature (100 °C) via conventional hydrothermal. This study was conducted to determine the effect of the hydrothermal process holding time on the characterization of Na-P zeolite. Synthesis process via hydrothermal method was performed with different holding times of 10,15 and 20 h at a constant temperature of 100 °C. The synthesized material were characterized using XRD and SEM techniques. The results showed conventional hydrothermal process successfully converts geothermal waste into Na-P zeolite, zeolite A and sodalite. Increasing the holding time in conventional hydrothermal method has affected the material characterization of the synthesized zeolite.
