Experimental study of carbon dioxide adsorption on 13x zeolite in a fixed bed reactor

In this research, carbon dioxide absorption by 13x zeolite was studied in a fixed bed reactor. The adsorption experiments were carried out in a fixed bed with 1 m height and 10 cm diameter. The adsorption experiments were carried out to investigate adsorption operating parameters including temprature, pressure, gas flow rate and adsorbent amount. The analyses result showed that adsorbent diameter avarege is 1.92 nm and interface area is 697 m2/gr. The experimental result showed that adsorption rate of carbon dioxide was increased by increasing pressure and bed height and decreasing temperature. The evaltuation of adsorption isotherm data showed that the CO2 adsorption is physical and the adsorbent has high capacity. Also the isotherm data was evaluated with different isotherm models and the results showed that Frendlich model with correlation coeffient 0.999 has good agreement with experimental data.
