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 کاملEsterification of Waste Cooking Oil Followed by Transesterification by CaO Nanoparticles: Application of Taguchi Methodology
In order to produce biodiesel from waste cooking oil and optimize its yield, a two-stage process of esterification/ transesterification has been used in this study. First, we used the acidic catalysts H2SO4 in order to diminish the content of free fatty acid (FFA) in oil that caused reducing the oil acidity from 6.1% to 0.57% through esterification. Then, the biodiesel was produced by transeste...
متن کاملBiodiesel Production from Used Cooking Oil
Production of biodiesel was involved transesterification process that implicated the reaction between used cooking oil and methanol with aid of KOH. The reaction was carried out at 15 min, 30 min, 60 min, 90 min, and 120 min to evaluate the effect of reaction time on the yield of fatty acid methyl ester (FAME). The highest yield of FAME was obtained at reaction time 60 min. Besides that, the yi...
متن کاملBiodiesel Production via Transesterification of Low Grade Cooking Oil over Heterostructure Nano Particles of Ni/Mg/Al2O3 Catalyst
Biodiesel which were synthesis from transesterification reaction in the present of heterogeneous base catalyst has been intensively studied over the last decades. This catalyst has an excellent result in producing high percentage conversions of biodiesel without further purification and cleaning process which contribute to the water pollution and high water content in biodiesel product. So, thi...
متن کاملInvestigating the Batch and Continuous Transesterification of Linseed Oil by Using a Alkaline Heterogeneous Catalyst in a Packed Bed Reactor
Both the continuous and batch transesterification of linseed oil were examined in order to maximize the fatty acid methyl esters (FAME) yield. The continuous process was conducted in a packed bed reactor using calcium oxide as a heterogeneous catalyst. In addition, the impact of two variables, namely the molar ratio of methanol to oil and the flow rate (ml/min), on the FAME yield were stu...
