Waste cooking oil, Impregnation, Egg Shell, CaO, Biodiesel

This research explores the use of used cooking oil as a primary feedstock in biodiesel production, with the addition of a calcium oxide (CaO) catalyst derived from eggshells. The process begins by filtering the used cooking oil to remove impurities, after which the oil undergoes tests to assess its density, viscosity, acid number, free fatty […]
