Process Intensification of Biodiesel Production via Supercritical Transesterification

Biofuels have gained lots of attention due to the rising interest in clean energy. Biodiesel is considered one of the most promising biofuels used in industry. Typically, biodiesel is produced using a base-catalyzed transesterification reaction with a feedstock of some vegetable oil or waste cooking oil (WCO). In this study, a more efficient and economical biodiesel production process is discussed. The process uses supercritical methanol and WCO as reagents in a transesterification reaction with no catalyst. To further improve the process, areas of opportunity for process intensification were investigated. From the process intensification study it was found that a membrane reactor combined with a purification step in the biodiesel production process will not only save space, but also time and money. This membrane reactor will greatly enhance the biodiesel production process and must be designed and put into practice to determine the effects it will have on the process
