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.
