• Study on Biodiesel Production: Feedstock Evolution, Catalyst Selection, and Influencing Factors Analysis (2025) · Energies · cited 42× · doi

  The reaction for direct esterification is reversible and the water generated as a by-product inhibits the forward reaction. Supercritical transesterification requires high temperatures, high pressures, and extended reaction durations, which substantially increase production costs. The use of catalysts in biodiesel production has limitations, such as the need for an excess of alcohol to drive the reaction towards ester formation.
