This study is aimed to convert the cigarette filters (CFs) into cigarette carbonaceous (CC) hydrochar as a green, cheap and economical approach to produce a novel adsorbent with added value and lower toxicity for CO₂ capturing. In this regard, cigarette carbonaceous (CC) hydrochar was obtained from CFs and used as support for ZIF-8-MOF growing, while the characteristics of samples were studied through FTIR, XRD, FESEM, and BET techniques. The CC-hydrochar/ZIF-8-MOF was used for the preparation of a fluid by dispersion in a 30 wt% MEA solution with a simple method without any surfactant. The CO₂-capturing performance of the prepared nanofluid was evaluated in a designed packed bed column, and the CCD-RSM technique was applied to investigate the contribution of four main operational parameters (gas flow rate, fluid flow rate, CC-hydrochar/ZIF-8 -MOF loading and CO₂ initial concentration) as the independent variables. The findings revealed that at optimum conditions the CO₂-capturing efficiency of CC-hydrochar/ZIF-8 MOF-based fluid can be dramatically enhanced over 32.36 %, compared to the bare 30 wt% MEA solution. It can be thus concluded that the presence of a few amounts of CC-hydrochar/ZIF-8 MOF in the base fluid could highly enhance the CO₂-capturing efficiency up to 99.15 %.

这项研究旨在将卷烟滤嘴（CFs）转换为卷烟含碳（CC）水炭，以绿色，廉价和经济的方法生产出具有更高附加值和更低毒性的新型吸附剂，以捕获CO ₂。在这方面，从碳纤维中获得了香烟碳质（CC）水炭，并用作ZIF-8-MOF生长的载体，同时通过FTIR，XRD，FESEM和BET技术研究了样品的特性。CC-hydrochar / ZIF-8-MOF用于通过不使用任何表面活性剂的简单方法将其分散在30 wt％ MEA溶液中来制备流体。一氧化碳₂在设计的填充床色谱柱中评估了制备的纳米流体的捕获性能，并采用CCD-RSM技术研究了四个主要操作参数（气体流速，流体流速，CC-hydrochar / ZIF-8- MOF加载量和CO ₂初始浓度）作为自变量。研究结果表明，与裸露的30 wt％ MEA溶液相比，在最佳条件下，基于CC-hydrochar / ZIF-8 MOF的流体的CO ₂捕集效率可显着提高32.36％以上。因此可以得出结论，基础流体中少量CC-hydrochar / ZIF-8 MOF的存在可以极大地提高对CO _2的捕集效率，最高可达99.15％。
