Synthesis of biodiesel via supercritical ethanol condition with heterogeneous catalyst

This Ph.D. thesis aims to gain a better understanding of non-catalytic and catalytic supercritical fluid (SCF) transesterification between ethanol and rapeseed oil to produce biodiesel mainly consisting of fatty acid ethyl esters (FAEE) for future reactor scale-up and process design. Another goal was to develop a new analytical approach employ high performance liquid chromatograph (HPLC) with the potential for in-line reaction monitoring to determine the compositions of liquid products such as FAEEs, triglyceride (TG), diglyceride (DG) and monoglyceride (MG).
