[摘要]利用高压搅拌式水合物实验装置,进行了四丁基溴化铵(TBAB)水合物储氢的研究。在恒容条件下,考察了水浴温
度、初始压力对水合物储氢特性的影响,并比较了TBAB水合物和四氢呋喃(THF)水合物的储氢性能。实验结果表明,在初始
压力7.2MPa、x(TBAB)=0.6%的条件下,水浴温度越低,生成水合物的诱导时间越短,储氡密度越大,水浴温度为0.5℃时储
氢密度最大(为0.095%);在水浴温度0.5℃、x(TBAB)=0.6%的条件下,初始压力越大,生成水合物的诱导时间越短,储氢密度
越大,在初始压力为8.4MPa时储氧密度最大(为0.109%);在水浴温度为0.5℃、初始压力7.2MPa的条件下,THF水合物的储
氢密度仪为0014%,远低于TBAB水合物的储氢密度(0.095%),TBAB水合物的储氧性能更好

I Abstract The characteristic of tetra-butyl ammonium bromide(TB AB)hydrates for hydrogen
storage was studied using experimental apparatus with high pressure stirring. The effects of water bath
temperature and initial pressure on the hydrogen storage under the condition of constant volume were
discussed. The characteristic of TBAB hydrates was compared with that of tetrahydrofuran(THF
hydrates. The results showed that under the initial pressure of 7.2 Mpa and the TBAB solution mole
fraction of 0.6%o, low temperature could lead to short hydrate formation time and large hydrogen storage
capacity, the largest hydrogen storage capacity was.095% at the water bath temperature 0.5 C. Under the
water bath temperature of 0.5 C and the TBAB solution mole fraction of 0.6%, high initial pressure
could lead to short hydrate formation time and large hydrogen storage capacity, the largest hydrogen
storage capacity was 0.109% at the initial pressure 8.4 Mpa. Under the water bath temperature of0.5 and
the initial pressure of 7.2 Mpa, the hydrogen storage capacity of THF hydrates was 0.014%o, smaller
than that of TBAB hydrates(0.095%0)
