Research

Kodama laboratory provides cutting-edge technology on research to the globe, contributing to improve the future of environment.

The research motivation is to develop a CCS (Carbon-dioxide Capture and Storage) process using engineering technology to reduce the emission of CO2. We are developing and evaluating of CO2 absorbents now. The physical properties of mixtures including supercritical fluids are investigated, developed the energy-saving process for CCS. Furthermore, thermodynamic properties such as Ionic Liquids which are becoming well known recently.

Current Research

1．Global Environmental Engineering

(1)ILs-CO2 Absorption and Recycling Process


1．Background of Research	One of global warming technology has been developed for separating and recovering carbon dioxide storage and sequestration, however, the current technology have a significant problem of regeneration cost for the absorbent of carbon dioxide selectively separated from thermal power plants and other large-scale fixed.
2．Research Objectives	In the present study, the absorbent (Ionic Liquids) can be driven at the room temperature will be synthesized. The absorbent will be clarified the mechanism of dissolution with the gas and the effect of gas absorption from the estimation model. The low-cost absorption process for greenhouse gas will be driven for construction.
3．Research Characteristics (incl. originality and creativity)	The carbon dioxide recovery process using Ionic Liquids can be built up simple operation of temperature and pressure changes. Carbon dioxide can also be recovered as liquefied or high pressure condition in the advantageous of isolation and storage. Thus, the energy cost can be significantly reduced, compared with the conventional techniques are required a huge energy cost for the absorbent regeneration.
4．Anticipated Effects and Future Applications of Research	The expected results of present study, the use of Ionic Liquids will be increased as electrochemical device, chemical reaction solvent, and catalyst. Therefore, the chemical process using volatile organic compound (VOC) slough off and can be expected to switch to environment-friendly process.
