These steps include saponification, acidification and esterification. The waste cooking oil was collected from the restaurants of Gujranwala . During saponification, molar ratio of WCO and caustic soda was reacted accordingly to a reported optimized value. Silica gel was used as dehydrating agent to absorb water from the synthesized biodiesel. The percentage yield obtained by this method was 79%. Physical and chemical properties like viscosity, density, flash point, cloud point, saponification value, acid value and ester value were examined to analyze the quantity of biodiesel.MS ThesisBiodieselWaste vegetable oilThesis
