In this paper was assessed the potential of biodiesel production from Jatropha curcas oil. The proposed process was simulated in the software Aspen Plus™ involving the stages of trans-esterification reaction, methanol recovering, purification of the obtained methyl esters, catalyst removing, purifying of glycerol and the energy integration through heat exchange networks (HEN). The biodiesel process was carried out through the catalytic reaction of transesterification of Jatropha oil with methanol using a molar ratio of methanol oil of 6:1, and with 1% w/w of NaOH (related to oil mass) as catalyst. Under these conditions, it is technologically feasible to carry out the production of biodiesel. With energy integration through the synthesis of HENs, reductions of 100% and 41.3% of hot and cold utilities were achieved. This way, the utility cost decreases 70.92%. The net present value (NPV) for the integrated process was 70.64% higher than the one corresponding to the non-integrated process under the same production conditions.

The research about utilization ash of coconut husk as source of base catalyst in aplication for reaction of transesterification from Jatropha curcas oil has been researched. Content of base compound in coconut husk ash was analyzed by AAS and acidy alkalimetry. The base catalyst was extracted using methanol, for transesterification reaction of Jatropha curcas oil. This method of biodiesel production by transesterification process used coconut husk ash catalyst by weight variation as much as 2%, 4%, 6%, 8% and 10% (w/w). Analysis of the quality of biodiesel is done with quality parameters acid number, iodine number, density, viscosity and water content in accordance with SNI 04-7182-2006 standards. The result of the research showed that potassium concentration as carbonat salt in the ash of coconut husk was 17,4% (w/w) and the conversion of biodiesel obtained from each catalyst in a row is 43,62%; 78,45%; 76,22%; 75,69% and 63,27% (w/w). Biodiesel optimum results obtained with the addition of the catalyst are 4% with density values of 0.86 (g / mL), the viscosity value of 3.23 (cSt), the value of water content 0.0352%, 0.12 acid number (mg KOH / g) and iodine number of 8.23 (g I2 / 100 g).The research about utilization ash of coconut husk as source of base catalyst in aplication for reaction of transesterification from Jatropha curcas oil has been researched.

The acid value of jatropha curcas oil is 9.41mgKOH/g. The most of fatty acids should be removed if base catalysts are adopted to catalyze the transesterification reaction for biodiesel production in case of soap formation. In this study, methanol and ethanol were adopted to extract the fatty acids in jatropha curcas oil. Then, it was catalyzed by calcium methoxide for biodiesel production. The extracted fatty acids can be used to produce biodiesel at supercritical or sulfuric acid conditions. The results indicated that the acid value of jatropha curcas oil decrease to 0.31 mgKOH/g from 9.41 mgKOH/g using ethanol extraction for 3 times at 25°C. The biodiesel yield exceeded 96% using solid base catalyst. The advantages of methanol and ethanol extractions are low oil loss and high biodiesel yield.
