Evaluation of Lubricating Properties of Palm Kernel Oil.

Abstract

The search for renewable energy resources continues to attract attention in recent times as fossil fuels such as petroleum, coal and natural gas, which are been used to meet the energy needs of man are associated with negative environmental impacts such as global warming. Biodiesel offered reduced exhaust emissions, improved biodegradability, reduced toxicity and higher carotene rating which can improve performance and clean up emissions. Standard methods were used to determine the physical and chemical properties of the oil, which includes the Density, Viscosity, flash/fire point, carbon residue, volatility and Specific Gravity were determined by chemical experimental analysis. The flash/fire points of the Heavy duty oil (SAE 40) and Light duty oil (SAE 30) is 260/300(°C) and 243/290(°C) respectively while the pour points of the samples are 22°C for palm kernel oil while 9°C and 21°C for SAE 40and SAE 30 respectively.
