Investigation of Dynamic Viscosity and Calorific Value of Algae Biodiesel Blend with n-Butanol Additive

Abstract

The transport sector primarily utilizes diesel fuel, which is a prominent energy source for various industries and applications. However, due to population growth, the increasing demand for diesel fuel leads to its depletion. This topic attracts many researchers looking for a solution through fuel alternatives, including the fuel properties of algae oil and its compatibility with diesel engines when combined with diesel fuel. To further understand the related topic, the study aims to explore the fuel properties, focusing on the viscosity and calorific value of Biodiesel Algae oil (BD) with n-butanol (nB). The Alge oil was prepared on the lab scale before blending to produce 4 different mixtures of Biodiesel. The results indicate that the blend 93BD7nB, which contained 93% of Algae biodiesel and 7% of n-butanol, obtained 0.168 Pa/s, which is in the required range in the standard limit ASTM D6751 whereas the calorific values for all samples above the standard limit EN 14214 indicate a good efficiency. In conclusion, this fuel blend exhibits promising potential for future utilization in diesel engine operations and provides an alternative solution for energy depletion.
