Description
Summary:The utilization of biodiesel-diesel blends has gained significant momentum in recent years. However, the unique properties of palm oil biodiesel demand careful handling compared to conventional diesel fuel whereas the most important is the preservation of oxidation stability. It is related to the resistance of biodiesel and its blends against heat and oxygen-induced oxidation reactions. This study focuses on the aging characteristics of palm oil biodiesel-diesel blends (B10 to B50) which were impacted by varying pristine biodiesel oxidation stability by aging with air and heat exposure. The experiment of biodiesel and its blend aging was set up using the Accelerated method (EN 14112 / EN 15751) and Rapid Smale Scale Oxidation Test method (ASTM D7545). Furthermore, the effects of diesel fuel aging on high and low biodiesel oxidation stability were examined, including density, kinematic viscosity, water content, acid number, and lubricity. Based on the results, it was found that the aging time of palm oil biodiesel significantly influences the oxidative parameters of the biodiesel-diesel blends (B10 to B50). Moreover, prolonged aging resulted in decreased oxidation stability and increased viscosity, total acid number, and lubricity. These outcomes highlight how crucial it is to handle and store palm oil biodiesel properly in order to maintain the quality of biodiesel-diesel blends.
