PENGARUH WAKTU HIDROTERMAL PADA SINTESIS ZSM-5 (ZEOLITE SECONY MOBILE-5) DARI KAOLIN : MENGGUNAKAN TEMPLAT PEG (POLYETHYLEN GLYCOL)

Abstract

Kaolin as natural minerals contains silica and alumina therefore it is potential as basic material for synthesizing process of ZSM-5. This study aimed to carry out synthesizing zeolite from kaolin with addition PEG template by setting hydrothermal times from 24, 48 and 72 hours at a hydrothermal temperature of 140 °C. ZSM-5 synthesis was carried out at various ratio of SiO2/Al2O3 molar composition 150. Synthesis products were analized by XRD. The results showed that at hydrothermal times 24 hours and 48 hours were not produced ZSM-5, while at hydrothermal times 72 hours was obtained ZSM-5 with quartz impurities.
