Abstract
Biodiesel is a fossil fuel that is in demand to be developed because it is bio-renewable, biodegradable and environmentally friendly. Biodiesel produced from the transesterification reaction of vege Tab. oil using a base catalyst. CaO is the most developed catalyst for the reaction of transesterification of oil into biodiesel because it is cheap, the process is easy and has a high level of alkalinity. CaO is a cheap catalyst because it is easily obtained from natural ingredients. The use of CaO catalysts in the reaction formation of biodiesel continues to develop through modification with various porous materials and different oxide materials. In this paper, we discuss the development of CaO, the modification of CaO with a porous material and metal oxide, the mechanism of reaction of CaO and the kinetics of reactions that occur in the reaction transesterification of oil to biodiesel.
