Optimization Of Biodiesel Production From The Waste Cooking Oil Using Response Surface Method
Biodiesel is one of the renewable energy sources. Commonly, biodiesel is made from the vegetable oils and animal fats. The advantages of using biodiesel are it can reduce pollution and petroleum consumption. Waste cooking oil (WCO) is one type of feed stocks that can be used to convert into biodiesel by using transesterification process. In order to optimize the biodiesel production, Response Surface Method (RSM) from Minitab 16 has been used. This project is to ensure that petroleum supplies not run out and to reduce environmental effect at water and soil that come from WCO. The objectives of this project are to determine the empirical equation of biodiesel production and to optimize yield production with related to catalyst concentration, reaction temperature and methanol to oil molar ratio. Magnetic stirrers and digital analytical balance are types of apparatus that has been used in this experiment. The experimental results, shows that the maximum yield production that can be extracted from WCO is 82.6% by using 60 degC of reaction temperature, 0.8 wt. catalyst concentrations and 10:1 methanol to oil molar ratio. By using Minitab 16 to optimize the experimental results, it shows that 59.5 degC reaction temperature, 9.8:1 methanol to oil molar ratio and 0.74 0.92 wt. catalyst concentration must be used to get yield percentage more than 80%
