Catalytic Decarboxylation of Palm Oil to Green Diesel over Pellets of Ni-CaO/Activated Carbon (AC) Catalyst in Subcritical Water

EasyChair Preprint 7128

Abstract

There has been large interest to convert palm oil to green diesel. Green diesel is a hydrocarbon compound that is similar to the components in conventional diesel fuel, hence i tis expected as a substitute for conventional diesel fuel in diesel vehicle engines. The process to produce green diesel is also called the deoxygenation process, namely: the process to remove oxygenate components in oil or fat. The current study evaluated the performance of Ni-CaO/AC catalyst in the form of pellets by mixing a powder Ni-CaO/AC catalyst and phenolic resin. The aim of the present work is to investigate palm oil decarboxylation under sub critical water condition. The scope of this research includes: catalyst activity test carried out by decarboxylation in subcritical water with temperature variations: 300, 310, 320, and 330°C using pellets of Ni-CaO/AC catalyst. The decarboxylation products obtained were analyzed with Gas Chromatography Mass Spectroscopy (GC-MS). The results obtained in this study showed that the highest hydrocarbon yield of 28.22% with a selectivity of heptadecane (C17H36) of 10.28% at 330 °C. However, the highest selectivity of green diesel was 75.39% which was obtained at 320°C.
