Abstract

Factories used palm oil solid waste in empty bunches, shells, and fiber (coir) as boiler fuel. The combustion process in this boiler produces by-products in the form of fly ash and bottom ash. Oil palm fly ash and bottom ash content were 37.98% (100 kg/week) and 64.36% (3-5 tons/week), respectively. After refluxing of fly ash, the SiO2 content of 96.8% is used to synthesize ZSM-5. The synthesis was carried out with the aging variation of 6, 12, and 24 h, and without aging time at the temperature of 60 oC. The hydrothermal was carried out at a temperature of 150 °C for 10 and 18 h. The results show an amorphous phase over 10 h hydrothermal, and ZSM-5 has formed over 18 h hydrothermal. ZSM-5 was formed and sodalite phase without aging time for 18 h hydrothermal. Analcime and sodalite formed for 6 h aging time. ZSM-5, analcime, faujasite, and sodalite formed over 12 and 24 h aging time. With a longer time of aging, the analcime phase dominated. It caused the metastable MFI structure to open to transform into alumina-rich structures. The morphology of ZSM-5 synthesized with hydrothermal 18 h with 6 h of aging is spheric and trapezohedron
