Contribution of the Reactive Separation Process to Methanol Recovery and Biodiesel Characteristics..

The chemical reaction that takes place during biodiesel production is a reversible reaction between oil and methanol. As a result, the amount of methanol used exceeds the stoichiometric equilibrium to increase the reaction's conversion. After washing biodiesel, it's always difficult to get rid of the excess methanol. The aim of this research is to figure out how the reactive separation process affects methanol recovery and biodiesel properties. The transesterification reaction is performed in reactive separation equipment with palm oil as the raw material, NaOH as the catalyst, and super base CaO as the super base. The findings showed that using a NaOH catalyst, the reactive separation process could recover up to 55.88 percent of the methanol, and using a super base CaO catalyst, it could recover up to 52.94 percent. The biodiesel characteristics provided to meet the Indonesian National Standard criteria.
