BioavTur hydroprocessing conversion study from vegetable oil

Abstract

A study has taken on simulation of the bioavtur production process with 6 types of vegetable oil: kemiri sunan oil, kesambi oil, nyamplung oil, palm oil, soybean oil and sunflower seed oil to evaluate the conversion. Simulation executed with variation in hydrotreating operating conditions. Pressure varied from 1-5MPa with an increment of 1MPa and temperature varied from 250-350? with 10? increment. The result showed vegetable oils with shorter chains are more likely to have higher yield and conversion, compared to longer chain vegetable oils. Free fatty acid content also contributes positively to reaction conversion. By evaluating the side product, it showed the trend for the hydrodeoxygenation reaction path will continue to increase as temperature increases. On the other side, the trend for the hydrodecarboxylation path is greater as the pressure increases. By evaluating the selectivity of palm oil at 2MPa and 290?, it showed bioavtur selectivity at its peak at 3MPa and 290? or 300?.
