process, use of 2,3-dihydro-2,2,4,6-tetramethylpyridine and a medium for the absorption of CO2 from a gas mixture, as well as equipment for separation of CO2 from a gas mixture.

摘要

Absorbing carbon dioxide from a gas mixture, comprises contacting the gas mixture with an absorption medium, where the absorption medium comprises water and 2,3-dihydro-2,2,4,6-tetramethylpyridine. Independent claims are also included for: (1) an absorption medium for absorbing carbon dioxide from a gas mixture, comprising water, 2,3-dihydro-2,2,4,6-tetramethylpyridine and at least one organic solvent in the homogeneous phase; and (2) a device for separating carbon dioxide from a gas mixture, comprising an absorption unit, a desorption unit and an absorption medium conducted in the circular manner, comprising the absorption medium.
