Review on the progress of the first-generation biodiesel hydrogenation and upgrading

ABSTRACT

This paper reviewed the research status of biodiesel catalytic hydrogenation and electric field enhanced treatment of biofuels in recent years. The industrialization process, progress of biodiesel catalytic hydrogenation, and electric field enhanced treatment of biofuel in recent years are reviewed in the investigation. The future research direction of biodiesel hydrogenation development is dug out according to the strengthening effect of the electric field on a chemical reaction. Researches have shown that the charged multiphase reaction system under electric field has significant advantages in enhancing mass transfer and phase interaction. Selective catalytic hydrogenation in an electric field environment, using electric field enhancement combined with catalytic process for hydrogenation upgrading, can enhance the activity and stability of the catalyst, greatly improve the catalytic chemical reaction rate, and significantly improve its oxidation stability and cetane number. This is an active technical method for modifying and upgrading biodiesel as a high-quality automotive biofuel.
