| Abstract | Hydrodeoxygenated vegetable oil is asecond-generation alternative diesel. Oxygenin vegetable oil isremoved throughhydrodeoxygenation(HDO), decarbonylation (DCO), and decarboxylation (DCO2) astheothermain reactionsin synthetic diesel production.The final products are hydrocarbon compounds with C15-C18 carbons, similar to traditional petroleum diesel.This study investigated the reaction mechanism and a kinetic modelof synthetic diesel productionfrom stearic acid (SA) with anNiMo/Al2O3catalyst in the temperature range 270-300?C under excessive H2.The kinetic model consistedof mass balance equations and rate law equationsbased on pseudo-first-order reactions. A MATLAB programwas used for calculations. The results from thesimulation demonstrated the %distribution of hydrocarbon products based on the proposed model was in good agreement with the experimental data.Furthermore, the results showedthat the initial H2pressure greatly affectedthe composition of the hydrocarbon productsand the reaction time. Therefore, the suggested conditions for synthetic diesel production from SA werean initial H2pressureof75-80 bars, a reaction temperature of 300?C, an SA concentration of 5%wt, and a reaction time of 1.5 hours. These conditions produced an average low heating value of synthetic dieselof 44.22 Megajoule (MJ)/kg. |
