摘要：Biodiesel being a renewable energy resource possesses compositional variability based on the type of feedstock. Biodiesel is considered a cleaner burning fuel and can be used as pure B100 or blended with petro-diesel. In this study,biodiesel was prepared from pure cooking oils (soybean oil,canola oil,sunflower oil,corn oil) and their waste frying oils by base-catalyzed transesterification with methanol in presence of sodium hydroxide. The optimized experimental parameters were applied to achieve the maximum yield of biodiesel. Various fuel properties like kinematic viscosity,flash point,pour point,cloud point,total acid number,specific gravity,water and sediments,conradson carbon residue,sulfur contents,phosphorous contents,sulphated ash,cetane and copper corrosion were determined and found comparable to ASTM standards. Pure cooking oils,their waste frying oils and prepared biodiesels were characterized by FT-IR. The study showed that the biodiesel derived from waste frying oils can be a promising alternative of the biodiesel from pure cooking oils..
