Solvent extraction and performance analysis of residual palm oil for biodiesel production: Experimental and simulation study

Study on the Formation Mechanism of Cold-Rolled Sludge and the Biodiesel Production from Sludge

“… 39 The addition of excess methanol in the actual reaction further increased the yield by reducing the viscosity of the oil while increasing the mass and heat transfer, and more reagents would be wasted. 40 When the said molar ratio increased from 70:1 to 110:1, the increase in biodiesel yield was negligible (0.05%), which is due to the fact that the increased amount of methanol would lead the hydroxyl group to emulsification, 41 exacerbating the difficulty of product separation and ultimately leading to a slow increase in biodiesel yield. Meanwhile, the increase in methanol consumption resulted in an increase in operating costs and energy consumption for the removal of abundant methanol.…”

Oil removal from spent bleaching earth of vegetable oil refinery plant using supercritical carbon dioxide

“…Zulqarnain et al. [ 8 ] performed solvent extraction experiments to extract oil from palm oil mill effluent to produce biodiesel fuel. They also reported that the presence of the palmitic and oleic acids as major components in the palm oil and its residual oil may lead to the formation of palm-biodiesel fuel.…”

“…There are several techniques to extract oil from the solid matrix, i.e., mechanical technique, biological technique, and chemical technique, where each technique has advantages and disadvantages during the oil extraction process [ 7 , 8 , 9 ]. Mechanical technique was known as the most conventional technique for oil extraction from the solid matrix, where in this method, oil was extracted forcefully from the solid matrix usually under applied high pressures.…”

Production, optimization, and characterization of Ethiopian variant Prosopis juliflora based biodiesel

“…Water washing was particularly successful in eliminating both glycerol and alcohol since they were both very soluble in water. It also got rid of any leftover sodium salts and soaps [ 45 , 46 ]. In this investigation, water washing (three times) was employed to wash the contaminants out of the crude biodiesel.…”
