The expected scarcity of petroleum supplies and the negative environmental consequences of fossil fuels have spurred the search for renewable and non-traditional energy sources and sustained conservation of fossil fuel. Biodiesel is an alternative fuel for diesel engines that can be produced from renewable feedstocks such as vegetable oil and animal fats. These feedstocks are with an alcohol to produce alkyl monoesters that can be used in conventional diesel engines with little or no modification. Previous research has shown that biodiesel fuelled engines produce less carbon monoxide, unburned hydrocarbons, and particulate emissions compared to diesel fuel. One drawback of biodiesel is that it is more prone to oxidation than petroleum-based diesel fuel. During long term storage, oxidation due to contact with air (auto-oxidation) presents a legitimate concern with respect to maintaining fuel quality of biodiesel. This work reported the results of the study of oxidation on the physico-chemical properties of biodiesel produced from Palm oil (Elaeis guinensis Jacq) and its blend with diesel through the different period of storage life. This oxidation results in increase in kinematic viscosity, relative density and acid value. While the flash and fire point and calorific value are decreased as oxidation proceeds.

Abstract


The expected scarcity of petroleum supplies and the negative environmental consequences of fossil fuels have spurred the search for renewable and non-traditional energy sources and sustained conservation of fossil fuel. Biodiesel is an alternative fuel for diesel engines that can be produced from renewable feedstocks such as vegetable oil and animal fats. These feedstocks are with an alcohol to produce alkyl monoesters that can be used in conventional diesel engines with little or no modification. Previous research has shown that biodiesel fuelled engines produce less carbon monoxide, unburned hydrocarbons, and particulate emissions compared to diesel fuel. One drawback of biodiesel is that it is more prone to oxidation than petroleum-based diesel fuel. During long term storage, oxidation due to contact with air (auto-oxidation) presents a legitimate concern with respect to maintaining fuel quality of biodiesel. This work reported the results of the study of oxidation on the physico-chemical properties of biodiesel produced from Palm oil (Elaeis guinensis Jacq) and its blend with diesel through the different period of storage life. This oxidation results in increase in kinematic viscosity, relative density and acid value. While the flash and fire point and calorific value are decreased as oxidation proceeds.
