Abstract

A novel magnetic solid catalyst CaO/NiFe 2 O 4 were prepared, which not only solved the separation problem of the small particle cat alyst, but also improved the yield for synthesis of biodiesel and the recovery rate of catalyst. Compared with CaO and another magnetic solid catalyst CaO/Fe 3 O 4 , CaO/NiFe 2 O 4 exhibited higher magnetic strength and catalytic property. Under the conditions of catalyst dosage of 1.0 wt. %, temperature of 70 °C , methanol/oil molar ratio of 15:1, the reaction yield reached to 95.5 % in 5 h. In the optimum reaction condition, the biodiesel yield can be maintained at 85 % after the catalyst was repeatedly used for 5 times, which is much better than those of CaO..
