Description: This study is aimed at evaluating biodiesel production from Parinari polyandra seed and its use as engine fuel. Oil was extracted from Parinari polyandra seeds obtained from bushes in Ilorin, Nigeria via solvent extraction method. The preparation of biodiesel from Parinari polyandra was carried out by transesterification reaction. The reactants for the transesterification process were the raw Parinari polyandra oil, anhydrous ethanol and calcined egg shell which was used as catalyst. The experiments were conducted within 60 - 65 oC temperatures, 60 - 120 min reaction time, alcohol to oil ratio 3:1 - 6:1 mol and catalyst concentration of 1 % by weight of oil. The fuel properties of Parinari polyandra biodiesel were determined using American Standard for Testing Materials methods. Optimisation of biodiesel production was done using response surface method. Engine bench tests were done using blends of biodiesel and Automated Gas Oil (AGO) from 5 - 20% of biodiesel with AGO (B5 ? B20, respectively) .
Oil yield of 53.13% and biodiesel yield of 90% were obtained. Specific gravity and kinematic viscosity @ 40 oC of biodiesel were 0.899, 3.905 Cst, respectively. Optimal biodiesel yield of 92.75% was predicted at 61.20 ?C temperature, 60 min, and 1 wt% of catalyst amount. Exhaust gas temperature increase from B5 except for slight decrease from 75 - 100% load condition when B20 was used. Biodiesel was found to have break thermal efficiency close to that of AGO.
