Translated Title
Study of the modification and CO2 adsorption property of peach activated carbon
Translated Abstract
Porous peach activated carbon(TAC)was modified directly using tetraethylenepentamine (TEPA)and HNO3 +TEPA,and the effect of modification on TAC’s adsorption of CO2 was investi-gated.The results show that the specific (BET)surface areas and pore volumes of TAC decrease after denaturization (oxidization process),while the pore diameter of TAC increases.Directly modi-fied TAC by TEPA has no significant effect on CO2 adsorption capability,however,TAC’s com-pound modification by HNO3 oxidation plus TEPA has significant effect on CO2 adsorption capabili-ty.The CO2 adsorption amount of N-TEPA-TAC measured increases from 0.39 mmol/g before modi-fication to 0.73 mmol/g at 303 K.The dosage of TEPA affects TAC’s modification result with the optimum dosage being 20 %.
