Paper Details

Biodiesel is one of the alternative fuels to diesel engines that reduce the use of petroleum diesel fuel andproduced from renewable biological sources. The seeds are generally discarded in order to more efficient use of Papaya.It is important investigating the use of seeds as source of oil. Mechanical extraction technique is used to extract oil.There are four ways to produce biodiesel, direct use and blending, Microemulsion, thermal cracking (pyrolysis) andtransesterification. The most widely use method is trans-esterification reaction because of Trans-esterification reaction isreduce the viscosity during the production of biodiesel. The purpose of this method is to reduce the viscosity of oil usingbase catalyst in the presence of methanol. So, Trans-esterification reaction is use to produced Fatty acid methyl ester(FAME) from papaya seeds oil at different experimental conditions. The parameters studied are; mass ratio of ethanol tooil, reaction temperature, catalyst concentration, and reaction time using completely randomized 34-1Fractionalfactorial design using Minitab Software in surface response methodology (RSM). Accordingly, the optimal conditions forthe production of fatty acid methyl esters from papaya seeds oil were determined as; 9:1 molar ratio of methanol to oil,0.5 % catalyst concentration by weight of oil, 120 minutes reaction time at a temperature 60°C. Validate optimizationcondition with Experimental. Analyzed papaya seeds oil and FAME. Fatty acid methyl ester Properties are found andclose to that of diesel fuel and also meet the specifications of ASTM standards.
