A Comprehensive Review of the Effect of Additives on Microalgae Biodiesel Performance and Emissions

Abstract

Abstract The production and utilization of biodiesel derived from microalgae have gained significant attention as a sustainable alternative to fossil fuels. However, the intrinsic properties of microalgae biodiesel can limit its performance and lead to undesirable emissions. This paper summarizes the impact of additives on microalgae biodiesel, focusing on their influence on performance and emissions. Additives play a crucial role in improving the overall quality and efficiency of microalgae biodiesel. They encompass a range of compounds, including antioxidants, stabilizers, and combustion enhancers. These additives have been studied extensively to elucidate their effects on fuel properties, engine performance, and exhaust emissions. By modifying the physicochemical properties of microalgae biodiesel, additives can enhance its stability, cetane number, and oxidative resistance, thereby promoting efficient combustion and reducing emissions of harmful pollutants. This review concludes that the usage of additives to the algae biodiesel leads to improved combustion performance and emission reduction.
