Diminishing fossil fuel reserves have stimulated research into biofuel as potential renewable and sustainable replacements for fossil diesel. The present research aims to characterize and investigate the behavior of mineral diesel and biodiesel blends. The biodiesel oil was prepared from sunflower oil collected from the local market. Binary blends of mineral diesel and biodiesel in various proportions were prepared, e.g. 5%, 10%, 15%, 20%, 25%, and named as B5, B10, B15, B20, B25.
Their various physicochemical properties were measured using standard ASTM/API methods, including specific gravity, API gravity, cloud point, pour point, aniline point, flash point, fire point, diesel index, viscosity, and distillation behavior. API gravity, aniline point, and diesel index decrease as the amount of biodiesel blended increases in the blend, while pour point, cloud point, flash point, fire point, and specific gravity increase with an increase in the amount of biodiesel blended in the commercial diesel oils.
