Pillared montmorillonite, as a representative of Sandwich like pillared interlayered clays ,caught many scientist"s attention not only because of its special structure of two-dimensional sheets but also its excellent activity of catalysis and adsorption. It is well documented that the method to prepare PILM, ion-exchanging, needed a long periods and was affected by many factors, and that the product had low thermal stability especially hydro-thermal stability which was the primary obstruction of its using in large-scale production. At the same time, PILM was well documented prepared with Na-montmorillonite, while there were a few documents about PILM prepared with Ca-montmorillonite. The large cost of remodel of Ca-montmorillonite to Na-montmorillonite was another obstacle of the application of PILM, while Ca-montmorillonite was widely distributed in nature, as a result, to prepare PILM with Ca-montmorillonite has practical significance. What"s more, PILM was mainly studied as a catalyst in oil refining process till now, but rarely documented in other catalysis reactions, especially in coal liquification filed which also needed high activity catalyst.
以柱撑蒙脱石为代表的具有"三明治"结构的柱撑粘土矿物因其特殊的二维孔道结构和优良的催化和吸附性能近年来成为国内外广泛关注和研究的热点,但是目前国内外大量报道的PILM制备大多采用离子交换法,生产周期很长,影响因素很多,并且产物热稳定性不够高,特别是水热稳定性较差,这是其不能在实际中大规模生产和应用的主要障碍,因此制备一种高稳定性的PILM意义非常;文献中大量报道的都是钠基蒙脱石合成的柱撑粘土矿物,传统的离子交换法必须将钙基蒙脱石钠化改型,其成本相当高,而自然界中大量存在的却是钙基蒙脱石,直接用钙基蒙脱石合成柱撑粘土矿物有很现实的意义,但目前这方面的报道却很少见;另外,迄今为止,PILM作为催化剂的研究领域主要在石油的炼制中应用,而在煤炭的液化中却鲜有报道,如果能在煤炭转化领域应用这一成果,其影响也将是相当大的。
