BIFUNCTIONAL Bi2O3/ZrO2 CATALYSTS FOR SYNTHESIS OF THIRD GENERATION BIODIESEL FROM NANNOCHLOROPSIS SP. LIPID
Microalgae as third generation biofuel have been found to simplify the shortcomings experienced by its predecessors. However, high free fatty acid content represents the major limitation which requires the microalgae lipid to undergo a two-step process to produce biodiesel. As an alternative, in thi...

Microalgae as third generation biofuel have been found to simplify the shortcomings experienced by its predecessors.
