Methanolysis of Triglycerides Using Jatropha Oil and Koh Catalyst
In this study, Jatropha curcas oil was used as feedstock for biodiesel production by alkali-catalyzed methanolysis. To establish the optimum conditions for biodiesel production, effects of certain factors were investigated, these factors are oil-to-methanol molar ratios (1:4 1:8), KOH catalyst concentrations (0.5 1.5% w/w oil), reaction temperatures (50 70oC), and reaction times (55 90minutes)....
متن کاملDynamic Modeling of Reversible Methanolysis of Jatropha curcas Oil to Biodiesel
Many kinetics studies on methanolysis assumed the reactions to be irreversible. The aim of the present work was to study the dynamic modeling of reversible methanolysis of Jatropha curcas oil (JCO) to biodiesel. The experimental data were collected under the optimal reaction conditions: molar ratio of methanol to JCO at 6 : 1, reaction temperature of 60°C, 60 min of reaction time, and 1% w/w of...
متن کاملSynthesis of biodiesel from Jatropha curcas L. seed oil using artificial zeolites loaded with CH3COOK as a heterogeneous catalyst
An environmentally benign process was developed for the transesterification of Jatropha curcas L. seed oil with methanol using artificial zeolites loaded with potassium acetate as a heterogeneous catalyst. After calcination for 5 h at 823 K, the catalyst loaded with 47 wt.% CH3COOK exhibited the highest efficiency and best catalytic activity. The easily prepared catalysts were characterized by ...
متن کاملCOMPARATIVE STUDY OF ENZYMATIC TRANSESTERIFICATION OF Jatropha OIL USING LIPASE FROM Jatropha curcas and Jatropha gossipyfolia
Biodiesel consists of monoalkyl esters of long chain fatty acids. It is produced from vegetable oils or fats either by chemical transesterification with methanol or ethanol. The cost of lipases and the relatively slower reaction rate remain as the major obstacles for enzymatic production of biodiesel as opposed to the conventional chemical processes. The enzymatic process offers several advanta...
متن کاملProduction of biodiesel from non-edible Jatropha curcas oil via transesterification using Bi2O3-La2O3 catalyst ABSTRACT The simultaneous esterification and transesterification of Jatropha curcas
The simultaneous esterification and transesterification of Jatropha curcas oil (JCO) was carried out in the presence of Bi2O3 (1–7 wt.%) modified La2O3 catalyst at atmospheric pressure. The catalyst were characterized by X-ray diffraction (XRD), BET surface area, desorption of CO2 (TPD-CO2) and NH3 (TPD-NH3). Under the optimal reaction condition of methanol/oil molar ratio of 15:1, 2 wt.% of ca...
