Synthesis of biodiesel from the pyrolysis process with different condition of temperature boundary

Abstract

For heavy-duty applications and power generation facilities, diesel engines are chosen over their spark ignition equivalents due to their better efficiency, robustness, and productivity. In order to solve the environmental and energy security concerns connected with these energy systems, research interests are currently being driven towards sustainable and renewable diesel fuels, such as biodiesel. However, the most difficult problem with producing biodiesel on a wide scale is its comparatively high cost compared to fossil-based diesel because of expensive feedstock and manufacturing expenses. Therefore, in order to increase the competitiveness of this biofuel compared to its petroleum counterpart, cost-efficient and environmentally friendly biodiesel production technologies must be created and continually improved. In the use of our automobiles, the used engine oil is disposed of in accordance with the usage depending on the engine running or the time duration. The pyrolysis process can be used to recycle this old engine oil. The pyrolysis reactor is the process component that is primarily involved in this pyrolysis. The related oil output and characteristics vary depending on the pyrolysis reactor's temperature (250℃ to 600℃). Basic properties including Calorific value, Cetane number, and kinematic viscosity are discovered to optimize the temperature for the pyrolysis process in this study on the effect of the operating temperature of the pyrolysis reactor on the oil yield. The optimal temperature was found as 550℃.
