Sažetak

The purpose of this paper is to determine the maximum adsorption capacity and the stability of impregnation agent ethanolamine to enhanced samples of activated carbon. Samples were characterized using BET surface analysis, BJH pore distribution and elemental analysis. Adsorption capacity was studied in a static regime in the pure CO2 atmosphere at the atmospheric pressure and at 30 °C and 50 °C. Stability of the impregnating agent bound to solid surface was studied by means of elemental analysis to specify the changes in nitrogen content before and after adsorption and before and after FID analysis. Flame-ionization detector was used to estimate the sum of organic compounds that were released from the solid surface at a given temperature. The results show that the best maximum adsorption capacity and impregnating agent stability among samples impregnated with MEA was for the molecular sieve 13X.
