HZSM-5 Catalyst for Cracking Palm Oil to Gasoline: A Comparative Study with and without Impregnation

Abstract

It is important to develop a renewable source of energy to overcome a limited source fossil energy. Palm oil is a potential alternative and environmental friendly energy resource in Indonesia due to high production capacity of this vegetable oil. The research studied effect of catalyst to selectivity of biofuel product from cracking of palm oil. The catalyst consisted of HZSM-5 catalyst with or without impregnation. The research was conducted in two steps, namely catalyst synthesized and catalytic cracking process. HZSM-5 was synthesized using Plank methods. The characterization of the synthesized catalysts used AAS (Atomic Absorption Spectroscopy) and BET (Brunaueur Emmet Teller). The cracking was carried out in a fixed bed microreactor with diameter of 1 cm and length of 16 cm which was filled with 0.6 gram catalyst. The Ni/HZSM-5 catalyst was recommended for cracking palm oil for the high selectivity to gasoline.

“…Typical catalysts for catalytic cracking or hydrocracking of triglycerides can be categorized into several types: (1) molybdenum-based sulfide/non-sulfide catalysts, such as NiMoS, CoMoS, CoMo/γ-Al2O3, NiMo/ZSM-5-alumina, and NiMo/SAPO-11 [2,6,7,[13][14][15][16], (2) Ni/Zn catalyst supported on HZSM-5 [14,17], (3) noble metals, including Pd/Pt catalyst supported on HZSM-5 [18]. Organic liquid product obtained can be divided into groups of gasoline, kerosene and gasoil.…”
