Overview on Advancement of Sustainable Heterogeneous Catalysts for the Production of Biodiesel

Biodiesel has comparable properties to diesel fuel; hence, it becomes a promising substitute to diesel fuel. The development of exceedingly effective biocatalyst is a key prerequisite for the production of biofuels, most especially biodiesel. Heterogeneous catalysts are regarded to be very prospective for transesterification process in biodiesel production owing to their numerous advantages, which include separation of catalyst from reaction mixture with ease, separation from reaction mixture with ease, regeneration, decreased corrosion, decreased cost and environmental friendliness. Heterogeneous catalysts can substitute homogeneous catalysts in situations that limit their efficiency. Hence, synthesized sustainable catalysts are required for increasing process performance, reduction in energy cost and production of cleaner products like ultralow sulphur biodiesel. Here, we gave a brief review on the advancement in sustainable heterogeneous catalysts for biodiesel production.
