摘要

木材干燥过程中会产生一系列有机挥发性气体(VOCs),这些气体对人体和环境都会带来巨大的危害。加强对木材干燥过程中产生VOCs的释放过程、释放控制和吸附的研究,即寻求环保高效的吸附剂是当前国内外研究的热点之一。在总结活性碳、活性碳纤维、活性碳纳米纤维、分子筛和蒙脱石基介孔材料等对VOCs吸附研究的基础上,探讨了新型MOFs材料在木材干燥工业过程中释放VOCs的应用可行性和发展前景。

关键词: 木材干燥挥发性有机物(VOCs) 吸附 MOFs材料

Abstract:

A series of volatile organic compounds (VOCs) will be produced in drying process of wood, which will seriously endanger human body and destroy the ecological environment. Currently, it has been an universal concern to control the release and adsorption of VOCs in drying process of wood industry and seek the eco-friendly, highly effective adsorbents. This review firstly summarized the VOCs adsorption on the activated carbon, activated carbon fiber, activated carbon nanofiber, molecular sieves and montmorillonite mesoporous materials. Secondly, the utilization of the novel and appropriate MOFs in the VOCs adsorption during drying process of wood is introduced. Finally, the application of MOFs materials based on the achievements is proposed.

Key words: wood drying volatile organic compounds(VOCs) adsorption MOFs materials
