Abstract
This review discusses the challenges and opportunities for adsorptive dehumidification for rotary desiccant dehumidifiers. As well, it presents an overview of current approaches and emerging technologies in the development of high-performance adsorbents for air dehumidification, including silica materials, activated carbons (ACs), supported haloid-based salts, zeolites, metal organic frameworks (MOFs), etc. The adsorption–desorption characteristics—that is, adsorption isotherms—and adsorption kinetics of different kinds of adsorbents are reviewed and further discussed. Some important issues to further advance the research and development of adsorptive dehumidification for rotary desiccant dehumidifiers are also summarized in this work.
