Green chemistry - a chance for alternative CO2 sequestration
Carbon sequestration technologies are still being modified and scientists worldwide are working on improving them or introducing new ideas. While fulfilling their main function of absorbing carbon dioxide, many of the CO2 absorbents currently used have various disadvantages, and some of them, at the same time, are harmful to the natural environment. Researchers from Gdańsk University of Technology are working on creation of an ionic liquid that will absorb harmful gas without adversely affecting the environment.
Ionic liquids are substances with special properties. They are consistent with the assumptions of the green chemistry. Properties that characterize modern ionic liquids are the following: negligible vapor pressure, high thermal stability (high decomposition temperatures), low melting points and low toxicity. These properties allow wide use in various fields of industry and scientific research. This raises high hopes in the energy industry. They are used in outlet points from various processes, where they can purify gases, e.g.
