Abstract: Palm fly ash is
biomass/waste in the palm oil industry.
Palm fly ash has high content of amorphous silica. ZSM-5 is one of synthetic
zeolite which is widely used as catalyst in industries. ZSM-5 has high activity
and selectivity to several hydrocarbon conversion reaction. Hence, ZSM-5 is
being investigated for the conversion of vegetable oil to hydrocarbon. It can be synthesized from silica and
alumina. Sources of silica that can be added to the ZSM-5 synthesis, are sodium silicate, hydrated silica, water
glass sol silica, gelled silica, clay, precipitated silicaand calcined silica.
ZSM-5 was synthesized free-template by using palm fly ash as silica source. In
this research synthesis of ZSM-5 was carried out in autoclave at 18 hours and
Na2O/Al2O3 molar ratio by various molar ratio from 30 to 40 and temperature in
the range of 150 to 190oC. The product was then analized using FTIR
method. The best ZSM-5 product was obtained at Si/Al molar ratio of 40 and
process temperature of 150oC.
