改性生物质活性炭的制备及其在乙烯分离中的应用研究进展
Advances in modified bio-based activated carbon for ethylene separation:Preparation and applications
摘要
Abstract
Bio-based activated carbon is regarded as an ideal adsorbent support due to its high specific surface area,tunable pore structure and abundant surface chemical properties,exhibiting remarkable advantages in high-efficiency ethylene separation technology.This paper systematically reviewed the research status of bio-based activated carbon as an adsorbent in ethylene separation,briefly outlined common precursor types and mainstream preparation methods,focused on analyzing the regulation mechanisms of physical activation and chemical activation on the pore structure of adsorbents,and discussed the reaction mechanism and application potential of bio-based activated carbon in ethyleneπ-complexation adsorption in depth.On this basis,the paper further pointed out the shortcomings of current research in terms of material stability,anti-interference ability in complex atmospheres,active site density and the research on ethylene adsorption mechanisms.Based on the aforementioned issues,it was proposed that future efforts should be devoted to constructing adsorbents with high cyclic stability and high adsorption capacity.Meanwhile,it was suggested to optimize adsorbents by combining process simulation and periodic evaluation technologies,so as to promote the industrial application process of bio-based activated carbon adsorbents and provide a new material system and technical pathway for the high-efficiency separation of olefins/alkanes.关键词
