“…So biodiesel production is an alternative to producing clean, biodegradable, non-toxic and renewable fuels [2][3][4][5][6][7][8]. At the same time, biofuel can be used as an additive to, or substitute fuel for, conventional diesel [9]. Recently, the production of biodiesel has attracted considerable attention as a biofuel that can contribute to decreasing our dependence to fossils fuels [10,11].…”

Waste oils are becoming increasingly more important as feedstock for the production of fuels and glycerol as byproduc. Optimization of homogeneous transesterification of waste frying oil (WFO) to biodiesel over hydroxide potassium (KOH) catalyst have been investigated. In this respect, response surface methodology (RSM) was applied to determine the relationships between methanol and WFO molar ratio (3:1–12:1), KOH concentration (0.5%–2%) and temperature (25–65 °C) on the conversion yield. Transesterification of WFO produced 96.33% maximum methyl ester yield at the optimum methanol/WFO molar ratio 7.3:1, KOH loading 0.5 wt. % and the reaction temperature was 58.30 °C. The physicochemical properties of optimized biodiesel met the requirements of the European Norm 14214, such as kinematic viscosity at 40 °C 4.57 mm/s2, the sulfur content 0.005 wt. %, and the density at 15 °C 889.3 kg/m3. This study also examined the accelerated oxidation of biodiesel and biodiesel/diesel blends under combined temperature and air effect at different periods of time while measuring their acidity. Results have shown that total acid number increased proportionally to the biodiesel content of the biodiesel/diesel blends from 0.5 mgKOH/g for B7 (7% (v/v) biodiesel and 93% (v/v) diesel) up to 2.8 mg KOH/g for B100 (100% biodiesel). The synthesized trans-esterified oil can be a potential alternative to petrodiesel, hence its application at an industrial scale. This work also reports some properties of crude glycerol (CG) derived from biodiesel from WFO. The glycerol yield (%), pH, water content (wt. %), density at 15 °C (g/cm3), and kinematic viscosity at 40 °C (mm2/s) was analyzed according to standard test methods.

“…When the alcohol to oil ratio increases generally over 15:1, one of the byproducts of the reaction glycerol dissolve in the excess alcohol and inhibits the transesterification reaction and thus reduces the yield [28,29]. At alcohol to oil ratio of 1:3 which is lower than the stoichiometric ratio, the alcohol vaporizes continuously and the biodiesel conversion may be affected [4,30].…”

“…It was reported that mass transfer is limited in the systems having a heterogeneous catalyst, thus the large quantity of methanol is used for the transesterification reaction. The authors studied that using an excess of methanol results in difficulties in recovering of biodiesel and also the process increases [4].…”

“…At the same time, the prices of these fossil fuels like oil and gas are increasing at a rapid rate [3]. The use of these resources causes harmful effects on the environment such as global warming, the release of greenhouse gases and air pollutants [4,5]. Also, the environmental agencies have laid strict regulations for reducing the pollution from the production of these fuels.…”

The energy crisis has become an important global issue because of the depletion of non-renewable fossil fuels. Therefore there is a need to explore alternative sources to solve the energy security problem. Different sources are available for energy production among which biodiesel is considered to be effective for reducing the dependency on fossil fuels. Biodiesel production causes less adverse impacts on the environment compared to petroldiesel and even the fuel properties are superior. Transesterification reaction was employed for producing biodiesel from various feed-stocks such as edible oil, non-edible oils, animal fats and used cooking oil etc. Thus, the present study investigates the various precursor materials used for biodiesel production. It also reviews the types of catalysts used and the effect of operating conditions on the transesterification reaction.

“…The biodiesel is formed as the light layer at the top and the glycerol obtained as heavy layer at the bottom, which are for producing cosmetics [21]. Different catalysts are used for the transesterification process such as alkali catalyst [22], acid catalyst [23], homogeneous catalyst [24] and heterogeneous catalyst [25] are used for the transesterification reaction.…”

Because of the increase in the energy demand in the global world, there is a need to find another source to fossil fuels. Biodiesel is one of the substitute resource since it is biodegradable in nature and causes less pollution. Fish feed stock one of the promising feed is investigated for biodiesel production. The fat extraction was done from fish waste using water as solvent. Then it was saponified with sodium hydroxide to reduce the fatty acid content. The optimization of experimental conditions was done by varying catalyst concentration and reaction temperature. The transesterification reaction was conducted in the presence of a potassium hydroxide catalyst to convert fatty acid ester of one type to another type. The properties of the produced biodiesel were tested as per the ASTM standards and the results were found to be meeting the engine combustion standards.
