Transesterification of Waste Cooking Oil for Biodiesel Production Using Modified Clinoptilolite Zeolite as a Heterogeneous Catalyst
Reduction of fossil fuels sources, increasing of pollution gases emission, and global warming effects increase the demand of renewable fuels. One of the main candidates of alternative fuels is biodiesel. Biodiesel limits greenhouse gas effects due to the closed CO2 cycle. Biodiesel has more biodegradability, lower combustion emissions such as CO, SOx, HC, PM and lower toxicity than petro diesel...
متن کاملEnzymatic transesterification of Jatropha oil
BACKGROUND Transesterification of Jatropha oil was carried out in t-butanol solvent using immobilized lipase from Enterobacter aerogenes. The presence of t-butanol significantly reduced the negative effects caused by both methanol and glycerol. The effects of various reaction parameters on transesterification of Jatropha oil were studied. RESULTS The maximum yield of biodiesel was 94% (of whi...
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 کاملHeterogeneous base catalysts for edible palm and non-edible Jatropha-based biodiesel production
BACKGROUND Transesterification catalyzed by solid base catalyst is a brilliant technology for the noble process featuring the fast reaction under mild reacting condition in biodiesel production. Heterogeneous base catalysts are generally more reactive than solid acid catalysts which require extreme operating condition for high conversion and biodiesel yield. In the present study, synthesis of b...
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...
