Description
Summary:As a non-toxic, renewable fuel with little or no modifications in diesel engines, biodiesel has the potential to replace diesel fuel. Biodiesel produced from used cooking oil reduces the total processing cost, minimises pollution and environmental degradation. Accordingly, there is a need for scale-up production. In this study, two steps procedures: acid-catalysed and transesterification were employed to reduce the free fatty acid (FFA) content of waste cooking oil for an improved biodiesel yield. Furthermore, some physicochemical properties such as flash point, cloud point, pour point, density, sulphur content, and viscosity were measured according to the ASTM Testing Method. A rare 96.3% biodiesel yield was achieved using the two steps, and the physicochemical properties of all blends were in line with the set standards. Unlike conventional industrial diesel production, individuals can use the techniques in this study to maximally produce biodiesel from waste vegetable oil, to perverse the environment in addition to job creation.
