The Hydrodeoxygenation of Non-Edible Oil for Green Diesel Production

Hydrodeoxygenation has been given huge attention as a promising method to
renewable energy source. The purpose of this study is to synthesize green diesel from
non-edible oil of Jatropha and Rubber seed oil as feedstock and discuss on the
product distribution. It was proposed that a monometallic catalyst is suitable for
green diesel via hydrodeoxygenation. 15% Nickel/ γ-Alumina are to be used for all
the experiment and kept as a constant variable. Vacuum gas oil is introduced by
mixing with non-edible oil as feed to the reactor. The reaction was carried out in a
batch reactor in three hours’ time with a 1.5-2 grams of catalyst. Four different
operating pressures under 300oC were selected for green diesel production from pure
non-edible oil while only one best operating condition is for vacuum gas oil and nonedible oil mixture. Samples were analyzed by Gas Chromatography Mass
Spectrometry and Flame Ionization Detector.
