Investigation of Physical-Chemical Properties and Evaluation of Optimal Blend Ratio of Rice Bran Biodiesel: A Mathematical Regression Analysis Approach

摘要

Our research work mainly focusses on the examination of properties, both physical and chemical, of biodiesel blends among neat diesel at different volumetric proportions. Properties like viscosity; calorific value (CV); pour point (PP); cetane number; could point (CP); flash point and fire point are measured for each blending ratios, and it is examined against the relevant standards (USA ASTM D 6751; Europe EN:14214 as well as India IS:15607). Plot between the properties and different blending ratios is drawn, and regression equations (R2) are formulated from which biodiesel properties are predicted and compared by mineral diesel. From this investigation, the optimal blending ratio is projected considering the different properties of biodiesel.
