  13. This project aims to develop the photochemical system which can perform the conversion of CO2 and H2O into high energy products (hydrocarbon, organic acids, etc.) using solar energy. As the active element in this system, we have focused on two candidates, metal oxide semiconductor and metal complex photocatalyst. To improve their reaction efficiencies and product selectivities, modification of the semiconductor surface by metal particle loading and ligand modification of the complex species were studied and the significant enhancement of the reaction yields was achieved by palladium metal loading to the semiconductor and phosphorous ligand introduction to the rhenium carbonyl complex.

  13. This study aims to develop a new method for the sequestering of CO2 in deep sea as CO2 hydrate. Under the temperature and pressure conditions of deep sea, the mixture of CO2 and water forms the crystalline molecular complex, called CO2 hydrate clathrate. CO2 molecules is enclosed within the lattice formed by water molecules, which are strongly hydrogen bonded with each other. As the density of CO2 hydrate is higher than that of sea water, CO2 hydrate would be sequestered in deep sea. To investigate the feasibility of deep sea CO2 sequestering, it is necessary to study the physical properties of CO2 hydrate. The object of this study are to investigate the formation and dissociation processes of CO2 hydrate and its physical properties.

  13. The objectives of this research project are to elucidate the mecha- nism of nitrogen and nitrous oxides (N2O and NOx) formation and to develop new combustion technology for simultaneous control of N2O and NOx emissions from bubbling and circulating fluidized-bed coal combus- tors. The effects of operating conditions, and coal and combustor typeson the emission levels of N2O and NOx have been examined using experi- mental combustors. In addition, catalytic effects of CaO, MgO and hematite particles were examined to reduce the emission levels. Finaly a novel technique for simultaneous reduction of the emissions, the ITS System, has been proposed based on the above experience. The ITS Systemenables us to reduce N2O and NOx emissions respectively by over 85% and 60% in the bubbling fluidized-bed combustor.
