Pyrolitic conversion of palm oil into liquid fuel using protonated zeolite-X prepared from rice husk silica and aluminum foil as catalyst

Abstract

Zeolite-X was successfully synthesized based on silica of rice husk and aluminum foil with the variation of sodium silicate aging time of 24, 48, 72, and 96 hours with a crystallization time of 96 hours as evidenced by XRD analysis with a 2θ angle peak diffractogram pattern similar to the IZA standard. Zeolite-X with sodium silicate aging time of 24 hours is the best zeolite-X with XRF analysis with components Na2O 0.436%, Al2O3 33.933%, and SiO2 65.631%, and the SEM surface morphology shape crystal was homogeneous cubes. Protonated zeolite-X or zeolite H-X has been successfully synthesized through the ion exchange process of zeolite-X with 2M NH4NO3 solution which had been proven by XRF analysis to reduce Na2O from 0.436% to 0.179%. Zeolite-X and zeolite H-X have the same 2θ angle diffractogram pattern. In SEM analysis, the surface morphology of zeolite H-X had a formless surface morphology. Zeolite H-X was applied in pyrolysis experiments using palm oil to produce liquid fuel. Liquid fuel was analyzed by GC-MS with components 77% hydrocarbon, 16% acid, and 7% ketones.
