  13. In order to reduce the ecological impact of manufacturing, it is necessary to minimize the environmental burden of each part of the system. We have developed a new computerized simulation method for assessing the environmental impact of proposed new products and manufacturing processes. Inputs to the simulator include environmental loads, and product and facility information. The materials and energy which are input to and output from the system under analysis are measured in "Ecounits", an index which represents the total environmental burden of the resources used and system outputs. The output from the simulator allows calculation of the predicted increment in ecounits caused by operation of the system. During tests of the simulator, the environmental impact of a hypothetical factory producing mechanical components was predicted, and the simulation method was shown to provide realistic and useful data.

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. 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.

R&D studies on separation and enrichment films of CO2 (the main contributing greenhouse gas to global warming) from high-temperature exhaust gas are carried out using ceramics such as MgO,CaO,Al2O3,Sepiolite,Dolomite,rare earth oxides etc. The development of long-life and highly efficient catalysts to reduce the collected CO2 to useful synthetic gases (e.g., CO and H2) is also being studied using the PSRA (Pulse Surface Reaction Rate Analysis) method.

  13. The aim of this study is to develop the bromine-free halon replacements which have a comparative fire-extinguishing ability with that of Halons. Halons have a bromine atom for imparting the good fire extinguishing ability in the molecule, but their use was banned due to the reason for the destruction of the ozone layer by the bromine. The key point of our work is the use of CF3 radical in place of a bromine atom as a function of fire-extinguishing mechanism in halon replacements. This project consists of the molecular design of new Halon replacemnts of which molecular structure can genarate CF3 radical effectively on contace with fire and the evaluation as a fire-extinguisher.

  13. The objective of this study is to develop novel plant growth regulators(PGRs) for increasing the tapioca production yield and for stimulating the growth of important plants with high CO2 fixation ability. Fluorinated and chlorinated plant growrh regulators have been synthesized. It is found in the joint project with the Thai Tapioca Development Institute that both of the PGRs stimulated remarkably the tuber growth of tapioca. The chlorinated and fluorinated PGRs are useful for the preparation of saplings and the stimulation of the growth of many plants which should play an important role for the improvement of global environment.

  13. The aim of this study is to fix CO2 by the reaction with hydrogen in order to solve global warming. CO2 is converted to hydrocarbons by hybrid or Fe-type catalysts. Methane was obtained in 95 % yield by LaNi5alloy catalyst.
