  13. The purpose of this project is to make ultra clean carbonaceous material from coal andcoke by removing the sulfur and ash using caustic. Although caustic leaching process(molten or solution) has been recognized as an expensive process for desulfurization until now, it is an only process that can make high quality acivated or cleaned carbon from high sulfur and high ash solid fuel. Molten caustic leaching and impregnation in caustic solution followed by calcination process are investigated. recovery of caustic also studied in this project.

  13. Energetic materials like explosives generate high energy under very rapid reaction (detonation). In the reaction zone, pressure may reach hundreds of thousands of atms and temperature may reach thousands of degrees. The aim of this study is to utilize explosive reaction to destruction of toxic and incombustible wastes in solid and/or liquid state, and to develop a quite new technology of waste treatment with explosives.

  13. Deep aquifers(deeper than 800 meters below the groundwater surface) can store large amount of carbon dioxide as aqueous solution under high formation pressure. To evaluate the stability of the aquifer disposal of carbon dioxide, a natural-analogue study will be carried out on carbon dioxide behavior and CO2-fixation mechanism in deep aquifers and adjacent strata.

  13. Recently, pollution of valuable water due to daily waste water or industrial waste water has been spreading on the earthwide scale to become a world wide problem. The treatment of waste water using TiO2 photocatalyst is able to decompose toxic and bioresistant organic pollutants readily. In such water treatment studies, TiO2 powders in general have been utilized as photocatalyst. TiO2 film photocatalysts have several advantages:1)it is easy to treat,
    2)filtration is not necessary to separate catalysts from treated water, 3)continuous treatment of waste water is possible. In this study, the development of highly active TiO2 film photocatalysts prepared by sol-gel method, the research on the destruction of bioresistant organic pollutants and the development of water treatment system using the TiO2 film photocatalysts are being performed.
