Biodiesel Preparation from Styrax Confusus Hemsl. Oil Catalyzed by Magnetic Catalyst S₂O₈^2--ZrO₂/Fe₃O₄

Abstract:

Styrax confusus Hemsl., a promising energy plant, was used as raw material for biodiesel preparation in this paper. The transesterification was catalyzed by magnetic catalyst S₂O₈^2--ZrO₂/Fe₃O₄, prepared by chemical co-precipitation method. TEM images indicat that the average particle diameter of magnetic core Fe₃O₄ and catalyst carrier ZrO₂/Fe₃O₄ are 5-20 nm and 30-50 nm respectively. Because of its unique porous structure the BET surface area could up to 140.75 m²/g. The results show that a best catalytic activity is obtained when the solid catalyst impregnated in 2.5 mol·L^-1 (NH₄)₂S₂O₈, calcined at 400 °C for 3 h, and a high methyl ester yield could be obtained under the optimal reaction conditions of catalyst amount 4.5 % (wt/wt oil), molar ratio of methanol/oil 6:1, reaction temperature 65 °C and time 2.0 h.
