Book excerpt: In the last three months we studied the phase composition of the fly ash in order to better understand the important parameters in the zeolite formation process using fly ash. In addition, since the zeolites exist in powder form, for practical applications, some ways of binding them into a piece of material is necessary. For that purpose, we began exploring ways of forming porous materials using fly ash. It was found that mixing fly ash, phosphoric acid, and calcium oxide can generate a porous material with good integrity. Meanwhile, the research on forming mesoporous materials from fly ash continued. Some results on the formation of double lamellar phase was found during the study.

Book excerpt: The authors have been investigating the conversion of fly ash into mesoporous materials in the last several months. Although lamellar phase has been observed, the hexagonal phase has not. According to the literature, only the hexagonal phase survives after calcination. Therefore, the goal is to synthesize hexagonal mesoporous materials with fly ash. It was pointed out by Chen et al. that the Si/Al molar ratio in the precursor solution must be larger than 74 in order for the hexagonal mesoporous phase (MCM-41) to be formed. On the other hand, the Si/Al molar ratio in the fly ash is lower than 74. In the last three months, the authors did a systematic study on the effect of Si/Al molar ratio on the formation of MCM-41 phase. The Si/Al molar ratio was varied from 148 to 1, the smallest ratio allowed by the Loewenstein rule. It was found that the amount of Al in the precursor solution can be as high as Si/Al=1 without disrupting the formation of aluminosilicate mesoporous materials (MCM-41). As the Si/Al ratio in the precursor solution was varied, the structure and the physical properties of the MCM-41 materials were changed. Lower Si/Al ratios tend to have a smaller shrinkage in the d100-spacing after calcination and have higher X-ray diffraction intensity. Results indicate that as the Al content increases, the MCM-41 materials tend to have a thicker cell wall.

This book was released on 1996 with total page 7 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is shown that fly ash can be used to participate in the formation of mesoporous materials. The dissolution of silicate species changes the surfactant/Si molar ratio in the silicate-surfactant solutions precipitating the MCM-41 phase. The current results demonstrate that fly ash can be used to form mesoporous materials and the impurities in the fly ash is not detrimental to the formation of MCM-41 phase. Although the MCM-41 phase can be formed with fly ash in the silicate-surfactant solutions, no MCM-41 phase can be made with solutions of surfactant/Si=0.35. The study so far indicates that fly ash has the potential to be used to form mesoporous materials. However, in order to make further progress, the concentration of silicate and aluminate species in the solutions needs to be controlled. In other words, the chemistry of the fly ash solutions needs to be studied in more detail. In the next few months, the authors plan to study the effects of using different fly ash solutions for the formation of zeolites as the first step in controlling the chemistry of fly ash solutions. Once the chemical composition of the fly ash can be controlled, it may be possible to increase the amount of participation of fly ash to the formation of mesoporous materials.

This book was released on 1997 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this report, we present more detailed study on the microstructure and chemical compositions of the MCM-41 phase converted from Conemiaugh ash. The converted mesoporous material was analyzed by TEM and the Energy Dispersive X-ray Spectroscopy in the TEM. This part of the work was done in collaboration with Princeton University. The hexagonal mesoporous structure was found to have a pore size about 26. 1 Å with a Si/Al mole ratio of 13.4. In addition, we studied the conversion of several other fly ashes with a wide range of chemical compositions to mesoporous aluminosilicates. It was found that both Eddystone and Goudey fly ashes can be successfully converted into MCM-41 aluminosilicates. Moreover, besides working on the synthesis of aluminosilicate mesoporous materials by fusion of fly ash and Ca(OH)2 powder. The nitrogen adsorption/desorption isotherms and XRD patterns of this mesoporous material using Ca(OH)2 were similar to those of mesoporous material using NaOH. It is not clear at the moment whether the mesoporous materials using Ca(OH)2 contains any Ca or not. If it odes, then the mesoporous materials synthesized with Ca(OH)2 may be very useful for SO2/NO gas adsorption in pollutant emission control by the reaction between those gases with Ca.

This book was released on 2001 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Froth flotation technique is an effective and efficient process for recovering of ultra-fine (minus 74[mu]m) clean coal. Economical dewatering of an ultra-fine clean coal product to a 20 percent level moisture will be an important step in successful implementation of the advanced cleaning processes. This project is a step in the Department of Energy's program to show that ultra-clean coal could be effectively dewatered to 20 percent or lower moisture using either conventional or advanced dewatering techniques. The cost-sharing contract effort is for 36 months beginning September 30, 1994. This report discusses technical progress made during the quarter from July 1 - September 29, 1995.
