中文摘要	为量化分析充放气压力和充放气流率对活性炭储氢系统充放气过程热效应的影响,选择比表面积为1 800 m2.g-1的椰壳活性炭SAC-01作吸附剂、容积为540 mL的钢制压力容器为储存容器,在室温、4个压力(10.5 MPa、8 MPa、6 MPa、4 MPa)下,对容器进行氢的快速充放和通过质量流量控制器(MFC)设定气体流率下充放气试验.结果表明:在充放气的初始阶段,充放气流率较大,储罐中心温度在短时间内升高/降低到最大/最小值;储罐壁温度的变化特点与储罐中心的相似,但变化滞后且变化幅度较小.对比试验结果时发现,充放气流率一定时,充放气压力会影响吸附床的温度波动幅度,但不改变储罐中心上升/下降到温度幅值所需要的时间;充放气流率为影响吸附床温度波动的主要原因;采用慢速充放气可减缓吸附床的温度波动.; Comparative experiments were carried out for quantitatively analyzing factors influencing the thermal effect on a hydrogen storage vessel by adsorption on activated carbon.The vessel in volume of 540 mL,specially designed to locate thermocouples for recording temperature fluctuation in the central region and the boundary during the charge and discharge processes,was packed with coconut shell activated carbon SAC-01 which had an specific surface area 1800 m2·g-1 and a micropore volume of 0.65 mL·g-1.Charge and discharge tests were undertook at ambient temperature and four pressures(10.5MPa,8MPa,6MPa and 4MPa),comparisons were then made between quick charge or discharge without using mass flow controller(MFC) and the slow charge or discharge under the flow rate set by MFC.Results showed that quick charge or discharge caused a stronger thermal effect on the storage system in comparison with the slow charge or discharge,and charge or discharge at a higher pressure brought about a larger temperature fluctuation in the central region and accordingly a greater temperature gradient within the vessel.Results also revealed that the time for the temperature in the central region reaching its maximum or minimum was short and independent of the charge or discharge pressure,but it varied with the flow rate.Conclusions were drawn that the flow rate of charging in or discharging from the storage vessel was fundamental to the strength of the thermal effect;measures for weakening the temperature fluctuation in the initial charge or discharge state as well as the enhancement of the heat conductivity of the adsorbent bed were also crucial to the performance of the storage system.Charging or discharging at a lower flow rate was more preferable to weakening the thermal effect in the dynamic storage process of hydrogen.; 【作者单位】集美大学轮机工程学院福建省船舶与海洋工程重点实验室；【作者英文名】ZHENG Qing-rong,WANG Zhen-ting,CAI Zhen-xiong,WANG Ji(Marine Engineering Institute,Jimei University,Provincial Key Laboratory ofNaval Architecture & Ocean Engineering,Xiamen 361021,China)
