摘要/Abstract

摘要： 活性炭（ AC）因比表面积大、内部通道发达，被广泛用于除臭、烟气净化和水净化。但其水亲和力易致吸附饱和，阻碍有机物吸附，缩短寿命。本研究通过表面粗糙化预处理和丙基三甲氧基硅烷接枝，制备了超疏水活性炭，并应用于扬子石化烯烃厂 M-003 吸附罐。结果表明，超疏水活性炭对烯烃厂废水废气中 VOCS 的吸附效率显著优于原活性炭。此外，超疏水吸附剂可降低运营成本，满足环保排放标准，提升企业环保形象，节省环保投入，运营成本节省率超 32%，兼具经济和环保效益。

Abstract: Activated carbon (AC), known for its large specific surface area and well-developed internal channels, is widely used in odor removal, smoke gas purification and water purification. However, its hydrophilicity can lead to rapid adsorption saturation, impeding organic adsorption and shortening its lifespan. In this study, super hydrophobic AC was prepared through surface roughening pre-treatment and propyl trimethoxysilane grafting, and applied in the M-003 adsorption tank of Yangzi Petrochemical Olefin Plant. The results showed that the super hydrophobic AC significantly outperformed the original AC in adsorbing VOCS from the plant's wastewater and exhaust gases. Additionally, the use of super hydrophobic adsorbents can reduce operational costs, meet environmental emission standards, enhance the company's environmental image and save environmental investment costs with an operational cost savings rate exceeding 32%. This demonstrates the dual economic and environmental benefits of super hydrophobic adsorbents.
