The heterogeneous catalysis of transesterification of gmelina seed oil to biodiesel is evaluated. The oil was extracted from the seeds with n‐hexane by solvent extraction and characterized to determine its physiochemical properties. Response surface methodology was applied to optimize the effect of process variables on the biodiesel yield. The base‐activated clay catalyst performed as montmorillonite clay with the characteristic property of a Brønsted acid. It has an improved surface area after activation that enhanced its catalytic activity on transesterification reaction. Under optimal conditions, the biodiesel yield was 70.1 %, thus demonstrating that the model predicted well the biodiesel production.

梅花籽油的非均相催化甲醇转化为生物柴油

评价了mel子种子油向生物柴油的酯交换反应的非均相催化。将油状物从与种子中提取Ñ通过溶剂萃取-己烷和表征，以确定其生理化学性质。应用响应面方法来优化工艺变量对生物柴油产量的影响。碱活化粘土催化剂用作蒙脱土，具有布朗斯台德酸的特征。活化后具有改善的表面积，增强了其在酯交换反应中的催化活性。在最佳条件下，生物柴油产率为70.1％，因此表明该模型预测生物柴油产量良好。
