Patterns of CO₂ Absorption by a Calciferous Sorbent in a Flow Adsorber

An investigation is performed of the patterns of CO₂ chemisorption by the carbon dioxide sorbent Dräger 800+. The dynamics of changes in textural characteristics, phase, and chemical compositions of the material in the process of chemisorption at the level of individual sorbent granules are studied. The dependence of the period of the protective action of the sorbent on the height of its layer, and on the flow rate and concentration of carbon dioxide in the initial gas–air mixture is determined. Based on experimental data, an empirical equation is obtained that can be used to predict the period of protection by a layer of granules of Dräger 800+ absorber at known contact time and concentrations of carbon dioxide in the gas mixture.
