The CO2 capture capacity was measured using real flue gas with 8% CO2 and 12% H2O in a fixed-bed reactor at a temperature of 65 °C using breakthrough curves. The developed sorbent showed an adsorption capacity of 66.2 mgCO2/(gr sorbent). The stability of sorbent capture capacity was higher than the reference sorbent. The SO2 impurity decreased sorbent capacity about 10%. The free carbon had a small effect on sorbent capacity after 5 cycles. After 5 cycles of adsorption and regeneration, the changes in the pore volume and surface area were 0.020 cm3/gr and 5.5 m2/gr respectively. Small changes occurred in the pore size distribution and surface area of sorbent after 5 cycles.}, keywords = {Flue gas,CO2 capture,K2CO3/Al2O3,Solid Sorbent}, url = {https://ijogst.put.ac.ir/article_6620.html}, eprint = {https://ijogst.put.ac.ir/article_6620_8ffd847afa3f50a8344c66b9dc15a3dd.pdf} }
