Hydroprocessing of Jatropha Oil for Production of Green Diesel over Non-sulfided Ni-PTA/Al2O3 Catalyst
The non-sulfided Ni-PTA/Al2O3 catalyst was developed to produce green diesel from the hydroprocessing of Jatropha oil. The Ni-PTA/Al2O3 catalyst was prepared by one-pot synthesis of Ni/Al2O3 with the co-precipitation method and then impregnanting Ni/Al2O3 with PTA solution. The catalysts were characterized with BET, SEM-EDX, TEM, XRD, XPS, TGA and NH3-TPD. The Ni and W species of the Ni-PTA/Al2...

Biodiesel production from neem oil using two step transesterification
Currently, most of the biodiesel is produced from the edible/refined type oil using methanol and alkaline catalyst. However, large amount of non-edible type oils and fats are available in our country. In this study, crude neem oil is used as alternative fuel for biodiesel production. The difficulty with alkaline transesterification of these oils have contained large amounts of free fatty acids ...
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 کاملSynthesis of quinolines from glycerol over tungstic acid functionalized mesoporous KIT-6 catalyst in aqueous medium
Mesoporous tungstic acid functionalized KIT-6 has been synthesized through a condensation of (3-chloropropyl) triethoxysilane and Si-KIT-6 followed by substitution of chloromethylation functionalized KIT-6 by sodium tungstate dihydrate. The synthesized tungstic acid functionalized KIT-6 (W-KIT-6) was characterized by low and wide angle X-ray diffraction analysis (XRD), N2 adsorption-desorption ...
