摘要：采用溶剂热方法合成了介孔聚合吸附材料，利用扫描电子显微镜(SEM)，氮气吸附仪(BET)，红外光谱仪对合成的吸附材料进行了表征，并通过CO2吸附评价实验研究了不同聚合条件、不同工艺条件对吸附材料CO2吸附性能的影响。结果表明：聚二乙烯苯氨基化产物、二乙烯苯与吡啶共聚物、二乙烯苯与咪唑共聚物均为介孔结构，比表面积在200-800m2/g，孔径在20-50nm；吸附性能聚二乙烯苯氨基化产物＜二乙烯苯与吡啶共聚物＜二乙烯苯与咪唑共聚物，吸附性能的强弱与聚合物的碱性相关；聚合物的吸附性能与CO2浓度相关性最大，当CO2浓度达60%时，聚合物材料的吸附量可达0.2273g/g吸附剂。 Abstract: Using a solvent heating way to synthesize polymerization adsorption materials, Using scanning electronic microscope (SEM), nitrogen adsorption meter (BET), the infrared spectroscope to characterizate the synthesised adsorption materials, and study the influence of different polymerization conditions and technological conditions to CO2 adsorption performance of adsorption materials through the CO2 adsorption appraisal experimental. The results indicated that the divinyl benzene polymerization ammoniation product, the divinyl benzene and pyridine polymer, divinyl benzene and imidazole polymer pertain to mesoporous structure, it’s surface area in 200~800m2/g, pore size distribution in 20~50nm; The adsorption performance of divinyl benzene and imidazole polyme is best, the adsorption performance of divinyl benzene polymerization ammoniation product is poor. The superiority of adsorption performance with polymer alkaline related; When CO2 concentration reaches 60%, the adsorption quantity of polymer can reach 0.2273g/g adsorbent; The polymer adsorption performance and the CO2 density relevance are biggest, when the CO2 density reaches 60%, The polymer material's adsorptive capacity may reach the 0.2273g/g absorbent. The influence of CO2 concentration on polymer adsorption performance is biggest. |

第一句的后面部分你自己讲语态改改。 The results indicated that the divinyl benzene polymerization ammoniation product, the divinyl benzene and pyridine polymer, divinyl benzene and imidazole polymer pertain to mesoporous structure with surface area between 200 and 800m2/g, pore size distribution between 20 and 50nm. |
