In the paper was presented introduction of Polish soda lime (produced by the Chemical Company Dwory SA) successfully used for filling the carbon dioxide scrubber of a regene-ration system built in KOBBEN class submarines for eliminating carbon dioxide from itsatmosphere without any additional construction changes. Research on the atmosphere re-generation was carried out on a KOBBEN class submarine. The initial CO2 concentrationwas achieved by releasing content of two cylinders filled with CO2/N2 gas mixture. Fur-ther CO2 emission adequate to its maximum production by the ship's crew during bre-athing, was simulated by means of a constant emission simulator.The time of the preventive operation amoun-ted to about 2 hours. The dynamic absorbing capacity of carbon dioxide was validated experimentally.
