<p>PURPOSE:To enhance the CO2-absorbing capacity by sticking amine-series organic substance having 1X10<-8>-5X10<-6>cm range of an average film thickness onto the surface of a porous material to obtain a solid substance and by using said solid substance as the adsorbent for CO2. CONSTITUTION:The respiratory gas in a closed space is sucked by a fan 1 and sent to a packed bed 2 packed with a solid adsorbent 3 onto which the amine-series organic substance such as ethanolamine, etc., is stuck so that the average film thickness on the porous material may grow to the range of 1X10<-8>-5X10<-6>cm in order to adsorb CO2 and the respiratory gas is sent back to the closed space through a filter 6. At another packed bed 7 the CO2-adsorbed adsorbent is regenerated by heating or by sucking under a reduced pressure and the CO2 is discharged to the outside space. The packed beds are switched by a valve 4.</p> |
