الملخص

Biodiesel production from Jatropha curcas L. (J. curcas) seed oil was investigated using high free fatty acids (FFA) (6.3 to 14.6%) and low FFA (1.6 to 1.76%) oils. The main fatty acids of J. curcas oil are oleic (39.60%) and linoleic (34.64%) acids. One- step alkali based catalyzed transesterification was carried out for low FFA ( 2) J. curcas oil a two step acid –base catalyzed transesterification was used. In the first step, FFA is converted to FAME using optimum parameters (methanol to oil ratio 7.5:1 at 1 w/w% H2SO4, 600 rpm at 60 oC) with conversion of (92.7%). In the second step, a 92.9 w/w% biodiesel yield was obtained using 4.5:1 methanol to oil ratio, 0.5 NaOH catalyst 65 oC and 600 rpm for one hour. The effects of reaction parameters of biodiesel production from low FFA J. curcas oil using one alkali transesterification using each of ultrasonic reactor (40 kHz) and multi reactor unit were determined. Optimum result was observed at 6:1 methanol to oil ratio, 0.5 % w/w NaOH to oil ratio, 60 oC and 30 minutes with a crude biodiesel yield of 86.5% and 98.55% FAME using ultrasonic transesterification, while a crude biodiesel with 97.71% FAME and 99% yield using multi reactor unit as optimum results was obtained at 6:1 methanol to oil ratio, 0.5% w/w NaOH to oil ratio 60 oC, 60 minutes and 400 rpm. Therefore, the experimental results show that J. curcas seed oil is an attractive feedstock for biodiesel production.
