摘要

针对传统沸石材料在低浓度煤层气提浓过程中疏水性与吸附分离性能难以兼顾的问题，本研究提出通过构建复合吸附剂的策略，提高其在潮湿环境下对CH

的分离性能。通过向疏水的高硅沸石介孔Y分子筛孔道内引入ZIF-8作为碳前驱体，经过炭化处理后制备了疏水的多孔炭@Y分子筛复合吸附剂。该材料形成了微-介孔分级结构，具有较高的扩散速率，并且对CH

的理想吸附溶液理论选择性由改性之前的2.39（介孔Y分子筛）提升至5.08。潮湿环境下的吸附性能测试及载水动态穿透实验也进一步表明，该材料在高湿环境中仍具有稳定的分离性能和良好的循环再生能力。本工作不仅为疏水沸石基复合材料的构筑提供了新思路，也为潮湿环境下低浓度煤层气的高效分离提供了一种具

有应用潜力的新型吸附剂。

Abstract

To address the trade-off between hydrophobicity and CH

separation performance in conventional zeolites for low-concentration coalbed methane enrichment

this study proposed a strategy to construct composite adsorbents to enhance separation performance under humid conditions. Specifically

ZIF-8 was introduced into the pores of hydrophobic high-silica mesoporous Y zeolite and subsequently carbonized to form a hydrophobic porous carbon @ Y zeolite composite. The resulting material features a hierarchical micro-mesoporous structure with enhanced diffusion rates

and its Ideal Adsorbed Solution Theory selectivity for CH

increased from 2.39 (mesoporous Y zeolite) to 5.08 after modification. The composite maintains stable separation performance and good regenerability under high-humidity conditions. This work offers a new strategy for constructing hydrophobic zeolite-based composites and provides a promising adsorbent for efficient CH

separation in humid environments.
