Two advances in biodiesel technology

Two advances in biodiesel technology

The fixed-bed reactor design and our new catalyst were at the heart of this approach. Although the wide versatility of our catalysts for esterification and transesterification were well recognized, development of other applications had to wait for process validation in biodiesel. Benefuel's Ensel® fixed-bed process is quite simple (Fig.1).
