主　　题：CO_(2)capture Supported polyamine Fibrous carbon Carbon microsphere Chemical adsorption 

摘      要：Supported polyamines are promising candidates for the chemical adsorption of CO_(2),the performance of which is highly dependent on the porous structure of *** this work,we synthesized a kind of fibrous carbon microspheres(FCMs)from environmentally friendly and low-cost *** synthesized FCMs have microspheric morphology and fibrous sub-architecture,and the carbon fibers interweave to form pores with large *** flexibility of the pores formed by the interweaving of carbon fibers also enable the supporting of high quantity of *** these features,pentaethylenehexamine(PEHA)was physically dispersed in the pores of FCMs to prepare PEHA/FCMs adsorbents,which were systematically characterized and investigated for CO_(2) capture *** is found that PEHA/FCMs adsorbents show excellent ability for CO_(2) adsorption,with the highest CO_(2) capacity of 3.90 mmol g^(-1) at 75℃ when using 10 vol%of CO_(2) for *** reversibility of PEHA/FCMs adsorbents for CO_(2) adsorption is also fairly good,and PEHA/FCMs adsorbents have strong ability for the selective adsorption of low-content CO_(2) from N_(2).
