Abstract
As well as its known diesel is very essential in daily life. Most of the transports need fuel to operate because fuels give required energy to activate the motor system when they are burned. However, fuels (especially fossil fuels) are limited and they run out rapidly each day. So, this situation leads to a new problem: finding alternative sources instead of fossil fuels. Biodiesel is considered as the primary alternative way instead of fossil fuels for future’s world. There are a lot of types of producing biodiesel from different sources such as vegetable oils and animal fats. In this experiment, I have aimed to produce biodiesel from wasted vegetable cooking oil. To obtain biodiesel production methanol should be react with wasted oil. By changing the some reaction parameter such as oil/methanol ratio, reaction temperature, reaction time, the concentration of the catalyst I want to determine the most efficient conditions for the production of biodiesel. The results showed that biodiesel production is possible under moderate conditions. The triglycerides in vegetable oil react with methanol and alkyl esters are formed. These alkyl esters are known as biodiesel. My studies showed that NaOH catalyst has a little effect on the efficiency of the transesterification reactions under studied conditions. The compositions of esters were investigated with the method of Gas Chromatography and it is found that the major compounds of biodiesel are linoleic acid, elaidic acid, oleic acid and palmitic acid methyl esters. Among which, the relative content of linoleic acid methyl esters was the highest one, reaching 59 %. Moreover, the optimum temperature is found as 60°C and hence, all the other experiments have been conducted at this temperature changing other parameters. After that, it is found that the reaction time has not any remarkable effect on the yield of methyl esters and excessive methanol had no significant effect on the yield either.
