Development of porous solid catalysts with strong basicity

合成了含高克拉克数元素K和Fe的各种混合氧化物固体碱材料。其中，K-Fe-Mn复合氧化物对甘油三酸酯中的三醋精与甲醇的酯交换反应表现出比CaO更高的催化活性。此外，我们还采用聚合络合法合成了具有高比表面积的K-Fe-Mn复合氧化物。其催化活性显著提高。因此，K-Fe-Mn复合氧化物是制备生物柴油的候选固体碱催化剂。

We synthesized various mixed oxide solid base materials containing of K and Fe which are elements with high Clarke number. Among them, K-Fe-Mn mixed oxide showed high catalytic activity for transesterification of triacetin, which is one of triglyceride, with methanol than CaO as a conventional solid base. Moreover, we achieved the synthesis of K-Fe-Mn mixed oxide with high BET surface by a polymerized complex method. Its catalytic activity was significantly improved. Therefore, K-Fe-Mn mixed oxide is found to be candidate solid base catalyst for biodiesel fuel production.
