Abstract
The effects of water content, added sodium hydroxide and the bulk density of absorbent granules on the absorption capability of calcium hydroxide based carbon dioxide absorbents have been studied. Water content and bulk density were found to have a significant influence on absorption capability and appear to be interrelated through a single quantity, the water film thickness surrounding individual absorbent granules. These findings support a reaction mechanism for the absorption process involving direct reaction of gaseous carbon dioxide and solid calcium hydroxide granules in the presence of water.
