ADSORPTION OF LOW-VOLATILITY GASES： MATERIALS，MECHANISMS AND APPLICATIONS（低挥发性气体吸附：材料、机制与应用）

Low-volatility gases (LVGs) are increasingly recognized as critical contributors to atmospheric pollution and industrial operational challenges.Their low vapor pressures,strong surface affinities,and intrinsic toxicity enable them to participate in secondary particulate formation,while also causing condensation,fouling,and corrosion in emission systems.These dual environmental and engineering impacts highlight the need for effective purification technologies grounded in robust scientific understanding.This book delivers a unified treatment of LVG capture by adsorption,linking porous-material design with adsorption thermodynamics,kinetic models,and mass-transfer phenomena.It explains how pore architecture,surface functionality,and diffusion constraints determine selectivity and capacity,and it treats desorption and regeneration as integral to process sustainability and cost-effectiveness.The text integrates molecular simulation and multiscale modeling as tools to reveal adsorption sites,interaction energies,and diffusion pathways,thereby informing rational adsorbent design.Case studies and process-level discussions translate these insights into engineering strategies for flue-gas treatment,incineration off-gas control,nuclear fuel reprocessing,and other industrial scenarios.Combining fundamentals,modeling,materials,and applications,the book is a concise technical reference for researchers and engineers tackling LVG purification and adsorption-based gas treatment.

This book can serve as a reference for researchers and engineers engaged in gas adsorption separation research and applications,as well as a teaching material for teachers and students in related majors at higher education institutions.
