The properties, preparation technique, characterization method, pillaring mechanism and applications of PILM were summarized, and some questions (including thermal stability, and hydro-thermal stability, and pore structure et al) about PILM were pointed out in this paper.

本文首先概述了PILM物化性能、制備技術(shù)欧美性爱福利、表征方法、柱化機(jī)理及其應(yīng)用領(lǐng)域等方面的研究進(jìn)展，指出了PILM研究中存在的問題(熱穩(wěn)定性免费精品无码人妻夜多侵犯AV，水熱穩(wěn)定性和孔結(jié)構(gòu)等)。

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.
