The effect of palm biodiesel composition on the physical properties of Calophylluminophyllum-palm biodiesel mixture

Abstract

Abstract The increasing energy consumption and depletion of fossil fuels require the need for alternative source of fuels. Biodiesel is an alternative fuel developed and can replace or reduce the use of petroleum diesel. One of its development processes is to change fatty acid composition through the mixing of different raw materials namely Calophylluminophyllum and palm oil. Calophylluminophyllum oil is a non-edible raw, while palm oil is an edible raw materialwhich is abundantly produced. The research was carried out by processing palm and Calophylluminophyllum oil into biodiesel using transesterification. Furthermore, both kinds of biodiesel were mixed with 11 variations of the composition. The results showed that mixing biodiesel Calophylluminophyllum and palm oil produced positive results with decreased viscosity and increased calorific value.
