Abstract The transesterification reaction of sunflower, mustard and linseed oil with ethyl alcohol was studied using potassium hydroxide as a catalyst. physicochemical properties low-temperature characteristics the feedstock obtained products were studied. most preferred for biodiesel fuel production had been determined.

Waste cooking oil (WCO) was used as a potential feedstock for biodiesel production. High levels of free fatty acids (9.85% w/w) in WCO made it an undesirable substrate for direct transesterification reaction. To solve this issue, a two-step process was implemented in this research. Firstly, esterification reaction was performed in presence of sulfuric acid as a common acid catalyst to reduce th...

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...

Biodiesel, an environmentally friendly biomass-based fuel, is gaining popularity globally as a cost-effective way to meet rising fuel demand. However, the high cost of raw materials and catalysts continues drive up biodiesel production. An alternative feedstock with heterogeneously catalyzed reaction could be most stabilize industrial growth. Understanding these issues led idea using waste palm...

AlPO4 solid acid catalyst was prepared in order to use it transesterification reaction of edible oil after supporting with tungsten oxide. The maximum conversion obtained 78.78% at concentration (5gm.), temperature 70°Ϲ, 30/1 methanol/edible molar ratio, and time 5hr. study kinetics the indicates that has an 3/2, while value activation energy for is 51.367 kJ/mole frequency factor equal 26219.1...

The transesterification process of trimethylphosphate with ethanol and isopropanol is examined. It is found that the reaction does not proceed in the absence of base even at temperature up to 100°C, whereas in the presence of sodium alkoxide as a catalyst it takes place at room temperature leading to a mixture of mono-,bi-, tri-substitute esters as well as the minor by-products resulting from t...
