Kinetics of Palm Oil Transesterification Using Double Promoted Catalyst CaO/KI/γ- Al2O3
Double promoted catalyst (CaO/KI/γ-Al2O3) was used as the catalyst for transesterification of palm oil into biodiesel. The experiment was carried out in a batch reactor consisting of a three-neck glass flask (500 ml capacity) equipped with a reflux condenser, thermometer and magnetic stirrer. Kinet...
