Abstract In the present study, based on hydrothermal reaction, new hybrids containing metal organic frameworks MIL-101 (Cr) and nanoporous carbon (GCKP2) in different ratios from 10 to 50% were synthesized. The common methods such as Fourier transform infrared (FT-IR), thermogravimetric analysis (TGA), Field Emision Scanning Electron Microscopy (FE-SEM) and N2 adsorption-desorption were used for characterization of these hybrids. The prepared materials were accordingly employed as adsorbent for H2S removal process and the results showed adsorption of 10, 6.2, 7.9, 6.0 mmol/g at pressure around 9 bar for MIL-101, hybrids containing 10%, 30%, and 50% of nanoporous carbon, respectively. Furthermore, the adsorption equilibrium isotherms were used to describe the experimental data and the Langmuir-Frendlich equation appeared to provide a better fit for the H2S adsorption by all synthesized hybrids. Relatively high H2S adsorption capacity, easy and safe handling, and scalable use are some of the advantages of the present nanoadsorbents.

MIL-101-纳米多孔碳作为一种新型纳米吸附剂去除气流中H 2 S的制备

摘要 在本研究中，基于水热反应，合成了含有不同比例的金属有机骨架 MIL-101 (Cr) 和纳米多孔碳 (GCKP2) 的新型杂化物。常用的方法如傅里叶变换红外 (FT-IR)、热重分析 (TGA)、场发射扫描电子显微镜 (FE-SEM) 和 N2 吸附 - 解吸用于表征这些杂化物。制备的材料相应地用作 H2S 去除过程的吸附剂，结果显示 MIL-101 在约 9 bar 的压力下吸附为 10、6.2、7.9、6.0 mmol/g，混合含有 10%、30% 和 50%分别是纳米多孔碳。此外，吸附平衡等温线用于描述实验数据，Langmuir-Frendlich 方程似乎为所有合成杂化物的 H2S 吸附提供了更好的拟合。相对较高的 H2S 吸附能力、简单安全的处理以及可扩展的使用是目前纳米吸附剂的一些优点。
