SYNTHESIS OF RENEWABLE DIESEL OIL FROM PALM OIL BY DEOXYGENATION OVER Ni BASED CATALYST SUPPORTED ACTIVATED CARBON

Abstract

Global warming and climate change have brought to the attention of many countries to use renewable fuels as energy sources. Developing renewable diesel fuel from vegetable oil is an alternative to replace die sel oil from fossil fuel. Renewable diesel production is performed by deoxygenating palm oil in a hydrogen free environment. Vegetable oil was deoxygenated with the help of a catalyst. Herein, the evaluation of catalytic deoxygenation of palm oil over Ni C aO catalyst supported by active carbon was investigated to compare the conversion of vegetable oil and the selectivity of products. The experiments were conducted at a temperature of 330 to 400 o C and first pressure of 20 bar in either N 2 gas or H 2 gas . Th e results obtained in this study showed that the deoxygenation reactions increased highly above the temperature of 350 0 C between 330 400℃. G reen diesel's highest yield and selectivity were obtained at 400℃ without external hydrogen gas
