BACKGROUND AND OBJECTIVE: Significant increase in carbon dioxide gas in the Earth's atmosphere has led to several problems, such as rising global temperatures, droughts and sudden changes in the climate.. The aim of this study is Evaluation of the capability of carbon dioxide greenhouse gas absorption using nano bio-activated carbon of Crataegus sanguinea core.
METHODS: This experimental study was performed on the time of carbon dioxide gas penetration in three subgroups with pressures (5,10,15 bar), flow rates (5,10,15 ml / min) and temperatures (20,30,60 ° C) at concentrations The equilibrium of 0 to 1 gr / ml was carried out through a carbon dioxide gas cylinder in a fixed bed column filled with 2 g of adsorbent synthesized by a carbon dioxide gas sensor. Nanobiocarbon absorbent from The Crataegus sanguinea core was pyrolyzed in 300ºC and activated at 600 ° C. Experimental data were examined with pseudo -first-order and pseudo-second-order models.
FINDINGS: Significant increase in the time of gas penetration was observed at a pressure of 15 bar (86.71±0.09 min, p≤0.001), temperature of 20 °C(67.68±0.013 min,p≤0.001) and flow rate 5ml/min(75.75±0.11 min, p≤0.001) in comparison with pressure values ​​of 5bar(37.14±0.03 min) and 10bar(60.33±0.27) and temperatures of 30ºC(54.36±0.03) and 60ºC(45.34±0.31) and flow rate of 5ml/min(53.8±0.013)and 15ml/min(45.09±0.09). Both first-order and second-order models had good fitting  with the coefficient R2 >98 on empirical data from absorption.
CONCLUSION:  The results of the study showed that with increasing pressure and decreasing of temperature and flow, the time of carbon dioxide breakthrough on the synthesized absorber increased.
