蒙脱石

And action process difference between modified mont morillonite powder and nature montmorillonite is also be analyzed in this paper

这些成果为蒙脱石悬浮载体技术的进一步发展和应用提供了理论基础。

Montmorillonite is a major host mineral for the pillaring reaction because of its 2:1 sandwich-like structure and the exchangeable cations between the layers.

蒙脱石由于其典型的2∶1型层状结构和大的层间可交换阳离子容量令其在粘土柱撑实验研究中占到了主导地位。

The dilute hydrochloric acid concentration, Ti/clay ratio, H/Ti ratio, the pillaring reaction temperature, the aging time of pillaring agent and the initial concentration of clay greatly affect the formation of Ti-PILC.

结果表明，盐酸的浓度、Ti／土比、H／Ti比、交联温度、交联剂老化时间和粘土悬浮液浓度等制备条件对钛交联蒙脱石的物化性能有较大的影响。

As a novel porous material, pillared montmorillonite is one of hotspots for mineral material research. Because of its big surface-to-volume ratio, variable apertures and strong acidity, PILM can be used as an excellent adsorbent and catalyst in petrochemical and environmental protection fields, and catch many scientists attention in recent years.

柱撑蒙脱石作为一种新型的多孔材料是当前矿物材料学研究的热点之一，因其具有大的比表面积、大小可调的孔径、较强的酸性而成为性能优异的吸附剂和催化剂，在石油化工和环保领域具有广阔的应用前景，近年来成为国内外广泛关注和研究的热点。

In this dissertation , Physical and chemical properties of raw material was studied first, then sodium model-modification of it was researched. Next, preparation of FILM in traditional process using montmorillonite after model-modification was in research. After that, we studied the preparation of PILM in hydrothermal process using montmorillonite without being model-modified. Finally, products in experiments were characterized and Analyzed by XRD, IR, DTA.

根据目前国内外的发展现状，针对存在的问题，本课题做了以下几个方面的研究：首先对采用的基质材料的物化性进行了研究；然后研究了其钠化改型的工艺方法；接下来研究钠化后的蒙脱石用常规工艺合成PILM；在此基础上提出并研究了水热法制备PILM和其柱化剂的新工艺；最后对制备的试样通过XRD、IR、DTA等进行了分析和表征。

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。

Objective: To establish a method for the determination of the content of Al2O3 determination in Smectite.

It is a simple and accurate operating method with good specificity and repeatability, and it was capable to effectively control quality of Smectite Power.

该方法操作简易，专属性及重现性好，可有效的控制蒙脱石散的质量。

In the two lake sediments, the character of d(001) peak shape of smectite changes in fine correspondence with sediment layers.

。泸沽湖和草海沉积物中蒙脱石d(001)峰形的变化与分层层理之间存在着比较好的对应关系。

Based on the case study of Dongying Basin, we evaluated quantitatively the contribution of illitization of smectite to the geopressure during diagensis processes.

在系统分析粘土矿物组成、成岩物理化学条件的基础上，模拟计算了蒙脱石伊利石化的动力学过程，计算了脱水造成的体积变化和硅钙释放量。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.
