Absorptive Capacity

The maximum amount of carbon dioxide that can be absorbed by soda lime is 26 L of carbon dioxide per 100 g of absorbent. The absorptive capacity of calcium hydroxide lime has been reported at 10.2 L per 100 g of absorbent.[116] However, channeling of gas through granules of soda lime or calcium hydroxide lime may substantially decrease this efficiency and allow only 10 to 20 L or less of carbon dioxide to be absorbed per 100 g of absorbent.[119]
