摘要

以丙烯腈(AN)为单体，二乙烯苯(DVB)为交联剂，采用悬浮聚合法制备了多孔聚丙烯腈聚合物(PAN)，进一步通过胺化反应制备了含有较高密度胺基的固态胺吸附材料. 利用N

吸附-脱附等温线、扫描电子显微镜(SEM)、热重分析(TG)等方法表征了吸附材料的结构和形貌. 研究了有机胺化试剂类型对所制备的材料结构的影响，以及吸附温度、湿度等对其CO

吸附性能的影响. 研究结果表明，当吸附温度为25 °C、流速为30 mL/min、CO

浓度为10%、有机胺为四乙烯五胺(TEPA)时，固态胺吸附材料PAN-TEPA对CO

的吸附量可达1.87 mmol/g. 水的存在能显著提高PAN-TEPA的吸附量，饱和水蒸气下，其对CO

的平衡吸附量为2.97 mmol/g. 动力学研究发现，Avrami模型能很好地拟合PAN-TEPA在不同温度下的吸附过程，揭示PAN-TEPA对CO

的吸附过程是物理吸附和化学吸附共同作用的效果. 经过10次循环再生吸附后，PAN-TEPA的吸附量仍可以达到初始吸附量的98%. 上述研究结果表明，PAN-TEPA对CO

具有良好的吸附性能和稳定的再生性能，其在CO

的捕集方面具有重要的应用前景.

Abstract

The objective of this study was to develop a novel solid amine adsorbent using porous polyacrylonitrile resin instead of mesoporous silica as support for CO

adsorption from flue gas. This solid amine adsorbent was prepared by a suspension polymerization of divinylbenzene (DVB) with acrylonitrile (AN)

followed by aminating with tetraethylenepentamine (TEPA). Scanning electronic microscope

nitrogen adsorption-desorption isotherms at 77 K

and thermogravimetry (TG) were employed to characterize the surface structure

porosity

and thermal stability of the solid amine adsorbent. Factors that could determine the CO

adsorption performance of the solid amine adsorbent

such as amine species

adsorption temperature and moisture

were investigated. The experimental results showed that the maximum adsorption capacity of CO

(1.87 mmol/g) wasachieved at 25 °C with CO

concentration of 10 vol%

the flow rate of 30 mL/min and TEPA as the organic amine. The solid amine adsorbent modified with TEPA (PAN-TEPA)

a longer chain amine among all amines used

showed superior amine efficiency and CO

adsorption capacity to the other two amine species with shorter chains. CO

adsorption capacity decreased obviously as the adsorption temperature increased

because the reaction between CO

and amine groups was an exothermic reaction. The presence of water could significantly improve CO

amount adsorbed on the adsorbent by promoting the chemical adsorption of CO

on PAN-TEPA. A higher equilibrium adsorption capacity (2.97 mmol/g) was achieved in the presence of moisture. Meanwhile

the kinetics study found that Avrami kinetic model was more fitted to accurately describe CO

adsorption than the Pseudo-first and Pseudo-second order models

indicating that both physical adsorption and chemical adsorption were involved in CO

adsorption. Moreover

this solid amine adsorbent could be regenerated with nitrogen stream at 75 °C

and it kept stable CO

adsorption capacity after ten cycles of adsorption-desorption. All these features indicated that the amine-functionalized porous polyacrylonitrile resin has a high potential for CO

capture and separation from flue gas.
