Studies of CO2 sorption by composite sorbents based on the active component (branched polyethyleneimine) dispersed using a porous support have been carried out. Composite materials with a branched polyethyleneimine content of 40 wt% were synthesised on the basis of four porous supports of different chemical nature, including two polymer materials, silica gel and aluminium oxide. The sorption properties of the obtained composite sorbents were studied in the process simulating the removal of CO2 from biogas (CO2 concentration in the gas mixture was in the range from 15 to 50 vol%). Based on the results of the sorption experiments, the values of the dynamic sorption capacity and enthalpy of CO2 sorption were determined for the materials. It is shown that the sorption properties of composite sorbents are mainly determined by the choice of a porous support. The analysis of thermal energy consumption for the regeneration of composite sorbents within the adsorption cycle was carried out, on the basis of which the promising materials for the extraction of CO2 from biogas were selected.
