金属有机架构物Cu-BTC低温吸附储氢数值模拟研究
Numerical simulation of hydrogen storage by adsorption on metal-organic framework Cu-BTC at low temperature
摘要
Abstract
Hydrogen storage by physical adsorption offers significant advantages,including high safety,high hydrogen storage density,and fast hydrogen charging and discharging rates,making it a highly promising method for hydrogen storage.Among the various materials,metal-organic frameworks(MOFs)have emerged as ideal hydrogen storage materials due to their highly ordered porous structures and tunable characteristics.To investigate the influence of thermal effects during the hydrogen adsorption process on storage performance,a numerical model of hydrogen storage by adsorption is established and validated.Subsequently,the hydrogen storage properties of Cu-BTC and activated carbon AX-21 tanks are analyzed and compared.Furthermore,the hydrogen storage capacity of Cu-BTC tank at different temperatures is explored.The results indicate that,compared with AX-21,the hydrogen storage capacity at room temperature increases by 12.8%when using Cu-BTC as adsorbent.When the storage temperature is reduced to 77 K,the maximum pressure in the Cu-BTC tank decreases to 0.97 MPa,and the hydrogen storage capacity increases by 174%compared with room temperature(300 K).These findings provide valuable insights for further research on the hydrogen storage capabilities of Cu-BTC materials.关键词
