液氢罐箱用MOFs吸附材料真空维持性能研究
Vacuum Maintenance Performance of MOF Adsorbents for Liquid-Hydrogen Storage Tanks
摘要
Abstract
Liquid-hydrogen tank containers have received increasing attention for hydrogen storage and transportation applications owing to their high hydrogen storage density and relatively low system cost.However,maintaining a high vacuum environment of 10-2 Pa in the interlayer of liquid-hydrogen containers remains challenging,with residual hydrogen contributing significantly to vacuum failure.Thus,high-performance,low-cost hydrogen adsorption materials and their corresponding vacuum maintenance mechanisms must be developed urgently.In this study,the adsorption characteristics of HKUST-1—a metal-organic framework—and its application mechanism in 40-foot(length:12 192 mm,width:2 438 mm,height:2 591 mm)liquid hydrogen tank containers were investigated.The results show that the self-synthesized HKUST-1,with a specific surface area of 1 426 m2/g and a bimodal pore structure,exhibited excellent physical adsorption potential.The material demonstrated reversible hydrogen adsorption in the liquid-hydrogen temperature range and maintained effective adsorption at extremely low pressures,thus serving dual functions for both cryogenic and ambient-temperature adsorption.Dynamic vacuum model results reveal that using a small amount of HKUST-1 at the cold end of the interlayer reduced the required amounts of both cryogenic and ambient-temperature adsorbents,thereby effectively enhancing the physical adsorption of residual hydrogen and retarding the increase of H₂ partial pressure under extreme vacuum conditions.This study provides a new material solution for vacuum maintenance in liquid-hydrogen storage and transportation equipment,as well as offers valuable insights into the safety design and operation of liquid-hydrogen tank containers.关键词
