Supercritical Methanol Extraction and Transesterification of Jatropha Curcas L. Seeds for the Production of Biodiesel – Process Parameters Study
In this work, optimization of supercritical methanol extraction and transesterification for the production of biodiesel was investigated using Jatropha curcas L. seeds. Several important process parameters including heat pre-treatment (45°C-105°C for 12 and 24 hours), particle size (0.5 mm-2.0 mm) and temperature (200°C-300°C) were being studied by varying one factor at a time. The experiment w...
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...
متن کاملJatropha curcas L.: Substitute for Conventional Energy
Jatropha curcas L. or physic nut belonging to family Euphorbiaceae is an all purpose, zero waste perennial plant. It is considered as a potential source of non-edible fuel producing plant along with its different medicinal properties and grows well in the tropical and subtropical climate in India. The seed contains 40-50 % viscous oil known as ‘curcas oil’. Petroleum based fuel are limited rese...
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 کاملDoes Biodiesel from Jatropha Curcas Represent a Sustainable Alternative Energy Source?
Various government agencies around the world have proposed vegetable oils and their conversion to biodiesel as a renewable alternative to fossil fuels. Due to its adaptability to marginal soils and environments, the cultivation of Jatropha curcas is frequently mentioned as the best option for producing biodiesel. In the present work the current situation of proven and potential reserves of foss...
