| Popis: | In this study, the effect of H 2 SO 4 on viscosity of methyl esters from Jatropha oil (JCME), palm kernel oil (PKOME) from Elaeis guineensis species, and coconut oil (COME) has been studied. Effect of methanol to oil molar mass ratio on yield of the three feedstocks has also been studied. Methyl ester yield was decreased by esterification process using sulphuric acid anhydrous (H 2 SO4). Jatropha methyl ester experienced a viscosity reduction of 24% (4.1–3.1 mm 2 /s) with the addition of 1% sulphuric acid. In this work palm kernel oil (PKOME), coconut oil (COME) and Jatropha oil (JCME) were used as feedstocks for the production of biodiesel to investigate optimum parameters to obtain high yield. For each of the feedstock, the biodiesel yield increased with increase in NaOH concentration. The highest yield was obtained with 1% NaOH concentration for all. The effect of methanol in the range of 4:1–8:1 (molar ratio) was investigated, keeping other process parameters fixed. Optimum ratios of palm kernel oil and coconut oil biodiesels yielded 98% each at methanol:oil molar ratio of 8:1. The physiochemical properties obtained for each methyl showed superior properties compared with those reported in published data. |
