ÔÎÄ£ºabout 100 mg of PEI/SBA-15 sample was placed into a U-shape quartz reactor and pretreated at 100◦C under helium flow (30 ml/min) for 20 min. When the temperature was reduced to 75◦C, CO2 sorption was performed by flowing CO2(10 ml/min) for 30 min. Then the temperature was decreased to 40◦C under the same CO2 flow. After that, the desorption experiment was executed by purging helium gas (50 ml/min) through the sorbent bed and ramping the temperature from 40 to 110 ◦C at a rate of 5◦C/min and holding at 110◦C for 20 min .The CO2 uptake or sorption capacity in millimole of CO2 per gram of sorbent (mmol/g-S) was calculated on the basis of the desorbed CO2 amount from the desorption curve, which was calibrated by a certain amount of CO2. ²»Ã÷°×ËûµÄCO2Îü¸½Á¿ÔõôËãµÄ£¬ÔÚÕâ¸öÎÄÕÂÖеÄʵÑéÊý¾ÝÓë֮ǰµÄʵÑéÊý¾ÝÓгöÈë¡£³ýÁËSBA-15µÄ½á¹¹²ÎÊýĿǰ»¹²»ÖªµÀÊÇ·ñÒ»Ñù£¬ÆäËûÌõ¼þ¶¼Ò»Ñù¡£Ê²Ã´½Ðcalculated on the basis of the desorbed CO2 amount from the desorption curve, which was calibrated by a certain amount of CO2.??? ³ö´¦£ºWang X, Song C.
