Sintesis Biodiesel Dari Cpo Menggunakan Katalis Heterogen H2so4/ Cao, Variasi…

Biodiesel is an alternative energy that is environmentally friendly and has low exhaust emissions when used in diesel engines. Biodiesel synthesis is carried out using the main ingredient, namely palm oil (CPO), but the high content of free fatty acids (FFA) (> 5%) contained in CPO is one of the factors that affect the performance of the catalyst. To overcome this problem, in this study, biodie…
