This study concerns the effect of water-soluble polymers with different structures on the sorption properties of unregenerable lime-based sorbents of carbon dioxide. It is shown that introducing water-soluble polymers into the composition of sorbents can either prolong or shorten the periods of their protective effect. To explain these findings, the porous structure of sorbents is studied, the transport of carbon dioxide is modeled using molecular dynamics, and coefficients of the diffusion of СО2 in water–polymer solutions are calculated. Modelling results correlate with data from sorption experiments: a stronger dynamic sorption capacity is obtained for a sorbent when a water–polymer medium with a greater coefficient of СО2 diffusion is added. These results can be used to optimize systems for separating carbon dioxide from gaseous mixtures and intensify mass transfer in systems for the photo- and electrocatalytic conversion of СО2 into useful products.
