摘要:
基于数值模拟分别探究了以MOF-5和AX-21为吸附剂时，不同泡沫金属孔隙率对在充气和放气过程中储氢罐内温度、压力、吸附量和总吸附量的影响。在充气阶段，储氢罐内添加泡沫金属可显著提高储氢罐内的有效导热系数，显著降低储氢罐的平均温度，提高储氢罐内平均压力，有利于吸附反应的进行。在放气阶段，加入泡沫金属可增加储氢罐内平均温度，从而促进氢气的脱附。在放气过程中，随着泡沫金属孔隙率的减少，脱附反应显著区域逐渐向罐体中心扩展，从而加速氢气的脱附和释放。存在最优的泡沫金属填充孔隙率使储氢罐内总的氢气吸附量最大。对于MOF吸附剂而言，最优的泡沫金属填充孔隙率为0.8；对于AX-21吸附剂而言，最优的泡沫金属填充孔隙率为0.9。
Abstract:The effects of different foam metal porosities on the temperature, pressure, adsorption capacity and total adsorption capacity in the hydrogen storage tank during the filling and degassing processes were investigated by numerical simulations with MOF-5 and AX-21 as adsorbents, respectively. In the filling stage, the addition of foam metal into the hydrogen storage tank can significantly improve the effective thermal conductivity in the hydrogen storage tank, reduce the average temperature and increase the average pressure in the tank, contributing to the adsorption reaction. In the degassing stage, the addition of foam metal can increase the average temperature in the hydrogen storage tank, which promoted the desorption of hydrogen. During the degassing process, with the reduction of foam metal porosity, the obvious area of desorption reaction gradually expanded toward the center of the tank, helping to accelerate the desorption and release of hydrogen. There existed optimal filled foam metal porosity leading to the maximum total hydrogen adsorption in the hydrogen storage tank. For MOF adsorbent, the optimal porosity was 0.8; for AX-21 adsorbent, the optimal porosity was 0.9.
