CHAPTER ONE
1.0 INTRODUCTION
1.1 Background of the Study
Fossil fuels are formed by natural process such as Anaerobic decomposition of buried dead organisms. The age of the organisms and their resulting fossils is typically millions of years and sometimes exceeds 650 million years (Tulsa and Tan, 2009)
Fossil fuels are non-renewable resource because they take millions of years to form and reserves are being depleted much faster than are being made. Fossil fuels such as petroleum, coal, natural gas and synthetic gas, which have been used to meet the energy needs of man, are associated with negative environmental impacts such as global warming (Munack, Schroder, Karh And Bunger 2001).
Besides, supply of this non-renewable energy resources is threatening to run out in a foreseeable future. More so, the use of fossil fuels contributes in the emission of green house gas, combustion of fossils also produce air pollutants such as Nitrogen oxides. Before now fossil fuel has been a raw material for producing lubricants and material like petroleum, diesel and graphite. Having seen all the negative environmental impact of fossil fuels, search for renewable energy resource and sources for energy and other application, like lubricants continuous to attract attention.
Lubricant is a substance capable of reducing friction by making surfaces smooth or slippery. Renewable energy resources like vegetable oils have been used to produce lubricants which are known as bio-lubricants. Bio-lubricants are prepared because they are biodegradable, non-toxic cheaper and have renewable resources unlike conventional mineral-base oils (Bandles and Bjorklund, 1992).
Bio-lubricants formulated from plants oils have the following advantages derived from the chemistry of the bases stock;
Higher lubricity leading to lower friction losses.
Lower volatility resulting in decreased exhaust emissions.
Higher viscosity index
Vegetable oil as a bio-lubricant has very low volatility due to the higher molecular weight of the triglyceride molecule. They have different unique properties compared to mineral oils, due to their unique chemical structure. Vegetable oils have a greater ability to lubricate and higher viscosity index. Superior anticorrosive properties are observed in vegetable oil and are induced by greater affinity for metal surface. High flash point over 300oc classify vegetable oils as non-flammable liquids.

ABSRACT - [ Total Page(s): 1 ]This study produced bio-lubricant with palm kernel oil and compared its quality with Tonimas Oil ( A commercial lubricating oil in the market). Palm kernel oil based lubricant was produced by dissolving 12.5ml of Zinc Dialkyl Dithiophosphate and 47.5ml of Ethylene propylene into 400ml of PKO and stiring them together to achieve a homogeneous mixture. The quality of the lubricant produced was compared with Tonimas oil using the following parameter; kinematic viscosity at 40oc and 100oc, specifi ... Continue reading---
