CONVERSION OF COAL WASTES INTO WASTE-CLEANING MATERIALS. FIANL REPORT (8/1/94-12/31/97)
In the beginning part of this project, we successfully converted the fly ash from the Eddystone plant of PECO Energy into faujasites and zeolite A. However, when we used the same approach to convert ashes from other power plants, it was not successful. Because of the differences in chemical compositions between different ashes, the conversion process has to be modified. Therefore the first goal in this project is to find a general method that can convert ashes of a wide variety of chemical compositions into zeolites. The zeolites synthesized from fly ash are then studied for their ion exchange behavior for the application in removing heavy metal ions from waste streams. In an attempt to broaden the applications of fly ash, investigation into the formation of mesoporous materials from fly ash was initiated. Mesoporous materials were discovered three years ago by scientists at Mobil and have been under active research by many researchers since then. Mesoporous materials have large surface areas with variable pore sizes in the range of >20 {angstrom}. Potential applications of mesoporous materials include catalysts, absorbents, molecular sieves, etc. If mesoporous materials can be converted from fly ash, it will open up another area of applications for fly ash. The second goal of this project is to convert fly ash into mesoporous materials.
