Algae Oil Transesterification by Ultrasonic Irradiation on Sn-nano Sulfated Zirconia-Silica Catalyst

Biodiesel production from algae oil by transesterification reaction using ultrasonic irradiation on heterogeneous catalyst was done at atmospheric condition to make the process sustainable and parsimonious. Ultrasonication reduces the reaction time as compared to the conventional methods and the solid acid catalyst gives 99.15% biodiesel yield which was obtained for oil to methanol molar ratio 1:10, catalyst 2 wt.% of oil, metal 0.4 wt.% of catalyst and 15min. reaction time. Heterogeneous catalyst and ultrasonic irradiation gives good yield and handling for biodiesel production.
