High temperature solid-catalyzed in-situ transesterification for biodiesel production

In-situ transesterification method is a simplified method for biodiesel production where the oil was simultaneously extracted and transesterified into alkyl ester in-situ in one single process. This process combines the steps of lipid (oil) extraction and transesterification. Methanol was used for t...
