Carbon dioxide is the main greenhouse gas and it’s amount still increases in the atmosphere. Air pollution and greenhouse effect caused by CO2 emission have become a major threat to the environment on a global scale. Carbon dioxide sequestration (i.e. capture and consequently geological storage) is the key strategy within the portfolio of actions to reduce CO2 emission to the atmosphere. CO2 capture is the most costly stage, therefore there is a need for search new solutions of this technology. For this purpose Na-X synthetic zeolites silver and PEI (poliethyleneimine) activated were examined. The results of SEM-EDS analysis showed the changes in structure of those materials after the treatment. It was observed that Ag occurs in Na-X structure what indicates a substitution Ag for Na ions in crystal lattice. After examination of wt% from EDS analysis it is seen that zeolite Na-X after silver impregnation becomes Ag-X zeolite. A distinct organic compound in the form of coatings were formed on Na-X PEI activated zeolite which is causing a sealing of pores in it’s structure. Further examination of these materials will focus on surface properties and experiments of CO2 sorption. However SEM-EDS analysis enable to determine the extent of activation. This is very important in determination of optimal conditions for such treatment in order to obtain better sorbent of CO2.
