Two times hydrolyzation of Fe~(3+) and Cr~(3+) was firstly pointed out in the process of pillar preparation with hydrothermal method. In order to improve the thermal stability, Fe/Cr-Si-pillaring agent solution was synthesized by hydrolyzing Fe~(3+) and Cr~(3+) solution on the surface of silica sol, and Fe/Cr-Si-pillared montmorillonite (Fe/Cr-Si-PILM) was prepared with conventional method and hydrothermal method. Because the technical innovation of preparation is the best way to improve the PILM properties, two novel methods (Microwave method and Ultrasonication method) have been studied to synthesize Fe/Cr-PILM.In order to expand PILMs new application in the field of coal conversion, catalytic activity of Fe/Cr-Si-PILM catalyst in LongKou lignite and ShenHua coal residue liquefaction was discussed and characterized in the last part of this paper.

研究证明：蒙脱石的预处理是可行的，我们以预处理后的Ca-M为原料，研究并优化了PILM的水热法制备工艺，提出了金属离子的二次水解法；为了提高PILM的热稳定性，我们自制了硅溶胶，合成了Fe／Cr-Si三元复合柱化剂，并制备了Fe／Cr-Si-PILM；在PILM合成中，制备技术的革新是改进PILM性能的重要方法，为此我们探索了微波合成法和超声波合成法在制备Fe／Cr-PILM中的应用；最后，我们选择龙口褐煤和神华煤液化残渣为研究对象，探索了Fe／Cr-Si-PILM催化剂在煤炭液化中的应用，希望能开拓PILM应用的新领域。
