Counntermeasures against CO2, the Origin of Global Warming

The conservation and improvement of the global environment is becoming an extremely important issue. R&D studies on separation and enrichment films of C02 (the main contributing greenhouse gas to global warming) from high-temperature exhaust gas are carried out using ceramics in NIRIN. The development of long-life and highly efficient catalysts to reduce the collected C02 to useful synthetic gases (e.g., CO and H2) to be used as raw materials for the chemical industry is also being studied using the PSRA (Pulse Surface Reaction Rate Analysis) method.

Automatic Measurement Technology of Acid Rain Component

The acid rain caused by S02 and NOx from various emissions is a major environmental problem not only in Europe and North America but also in East Asia. Therefore, it is very important to develop a monitoring network system for automatic measurement of acid rain and affected environmental waters. To develop a network system consisting of the combination of an advanced ion chromatography technology and a meteorological remote sensing technology for automatic measurement of the acid rain waters, several joint projects based on the cooperative agreement of environmental science and technology between NIRIN and the University Institutes in the Asia-Pacific region has been carried out since 1990.

Development of New Halon Substitutes

Halons have been used widely in computer rooms, museums, etc., because of their effective fire-extinguishing ability, cleanliness, and electrical non-conductivity. However, their use was banned due to the suspected depletion of stratospheric ozone by a bromine in the molecule. This project aims at the development of new perfluoroamine-type Halon substitutes which do not destroy ozone and have good fire extinguishing ability.
