Zeolite is a hydrated alumino-silicate compound having a main element which consist s of alkali and alkaline-earth cations, especially Ca, K and Na, with a general formula (LmAlx Sig O 2 nH 2 O) where L is a metal. Zeolite can be synthesized from a sample containing silica and alumina . The compounds conta in alkali hydroxide or organic base s . Palm kernel shells are one of the industrial wastes containing many minerals such as SiO 2 58.02%; Al 2 O 3 8.7%. The source of silica and alumina in oil palm shells is used as a base for making zeolites using the hydrothermal method in a reactor. Fine samples of palm shells were melted with NaOH at 500 ° nn C for 1 hour and diluted to produce sodium silicate reactants. Making sodium aluminate reactant is done by dissolving NaOH in distilled water and then heating and adding Al(OH) 3 to NaOH solution with stirring. Making zeolite is done by mixing sodium silicate and sodium aluminate reactants and the zeolite crystallization process is carried out using a hydrothermal reactor heated in the oven by varying the hydroternal temperature of 1200C, 150 ° C and 1800C for 8 hours. The synthesized zeolite was characterized using XRF, FTIR and SEM EDX. |
