A study to determine the relationships between the structure and the activity of the various amine-based CO 2 capture solvent was performed. We synthesized the sterically hindered amine (amine Y1) as the new absorbent with the modification of its che

Decreasing CO2 Emissions from coal fired thermal power plants is a critical issue in the world. Toshiba designed and built the CO2 capture pilot plant at Mikawa coal fired thermal power plant in 2009. Following this, we have developed not only an eff

We synthesized the sterically hindered amine A by an appropriate placement of alkyl groups. Quantitative 13C NMR spectroscopy was performed on 30 wt% aqueous solution of the amine A with different amount of CO 2 at 40 °C. The results suggested that

Although research and development (R&D) affects new value-added creation, including that related to environmental aspects, there is little literature dealing with the integration of R&D management and eco-value. Here, eco-value of technology is defin

A novel CO2 separation technique that employs the chemical reaction of lithium-containing oxides with CO2 has been developed. Since this method is effective in the temperature range of 450oC to 700oC, it has the advantages of enabling CO2 separation

We have discovered a series of lithium-containing oxides that immediately react with ambient carbon dioxide (CO2) up to 700°C. The products react and return reversibly to the oxides at a temperatures higher than about 700°C. The absorption capacity
