摘要

直接空气捕集（DAC）变湿吸附剂的研究多数是固体粉末状材料，不利于大规模工程应用。通过将活性炭（AC）与黏合剂甲基纤维素和膨润土复合，并进一步负载K

，制备了用于CO

直接空气捕集的K

/AC成型吸附剂，并通过表征测试及C

吸附性能测试，评估了其实用性能。实验结果显示，成型后的吸附剂具有良好的抗压强度和CO

吸附性能。随着成型吸附剂中AC含量的增加，其CO

直接空气捕集吸附量呈上升趋势。AC质量分数为60%的K

/AC-60成型吸附剂具有最优的抗压强度，其吸附量可达到0.319 mmol/g。研究结果为粉末状变湿吸附剂的成型和工业化应用提供了科学依据，对于开发实用化的DAC吸附剂具有重要意义。

Abstract

Currently

most research on moisture-swing adsorbents for CO

direct air capture (DAC) technology focuses on solid powder materials

which hinder large-scale engineering applications. By compositing activated carbon (AC) with binders such as methylcellulose and bentonite

and further loaded with K

a K

/AC shaped adsorbent for direct air capture of CO

was prepared. Its practical performance was evaluated through characterization tests and CO

adsorption performance tests. Experimental results indicate that the shaped adsorbent exhibits good compressive strength and CO

adsorption performance under DAC circumstances. As the AC content in the shaped adsorbent increases

the adsorption capacity for DAC shows an upward trend. The K

/AC-60 shaped adsorbent with an AC mass fraction of 60% has the optimal compressive strength and its adsorption capacity can reach 0.319 mmol/g. This study provides a scientific basis for the formation and industrial application of powder moisture-swing adsorbents

and holds great significance for the development of practical DAC adsorbents.
