Review Artikel KATALIS KALSIUM OKSIDA (CaO) BERBASIS BIO UNTUK PRODUKSI BIODIESEL
AbstractThe cost of biodiesel production itself is influenced by the basic ingredients for processing and also from the system used. The use of calcium oxide catalyst is intended because it has a good chance of the efficiency and effectiveness of the material that can be easily obtained in each region. Calcium oxide catalyst from waste also has an equal or even approaching chance of commercial calcium oxide. This review will show methods and discussion of the handling of the transesterification process in biodiesel with a mixture of methanol and catalyst that has been tested and the results of the different processes of each biodiesel. The performance of the process can be determined from the process to the reaction performance of the catalyst such as setting the number of catalysts used, the speed of stirring the mixture, the ratio of methanol to oil and the temperature and time of reaction. In order to obtain more economic value, the process of reusing the catalyst which has been reacted in the initial transesterification process can be carried out. The reuse of the catalyst for the next process can be carried out stably for 3 times of repeated use with the yields that are not far from the initial process.
