Проведены исследования сорбции CO2 композитными сорбентами, представляющими собой активный компонент (разветвлённый полиэтиленимин), диспергированный в порах мезопористого носителя (силикагеля). Показано, что по мере заполнения пор силикагеля полиэтиленимином эффективность сорбции CO2 активным компонентом снижается, а динамическая сорбционная емкость в расчёте на 1 г материала проходит через максимум. Определены значения энтальпии сорбции CO2 композитными сорбентами. Показано, что значения энтальпии сорбции CO2 зависят от доли заполнения пор активным компонентом и от характеристик пористой структуры носителя. Выполнен анализ потребления тепловой энергии на регенерацию композитных сорбентов в рамках адсорбционного цикла.

Studies of CO2 sorption by composite sorbents containing the active component (branched polyethylenimine) dispersed in the pores of mesoporous support (silica gel) have been carried out. It is shown that as silica gel pores are filled with polyethylenimine, the sorption efficiency of CO2 by the active component decreases, and the dynamic sorption capacity per 1 g of material passes through a maximum. The enthalpy values of CO2 sorption by composite sorbents have been determined. It is shown that the enthalpy values of CO2 sorption depend on the proportion of pore filling by the active component and on the characteristics of the porous structure of the support. Thermal energy consumption for regeneration of composite sorbents within the adsorption cycle was analyzed.
