| 摘 要： | 磷酸铝分子筛拥有规则的多孔结构,具有吸附、储存甲烷的能力,以前的研究报道多侧重于它们储存量的研究而对它们结构与吸附量关系的研究报道很少。实验研究了磷酸铝分子筛AlPO-53,SAPO-34和AlPO-5在温度273 K和303 K、压力100-2000kPa条件下的甲烷储存性质并讨论它们的储甲烷量与其结构之间的关系。在实验条件下,具有笼形结构的SAPO-34（0.38×0.38 nm）具有最大的甲烷储存量（2.35mmol/g,273 K,2000 kPa）,而具有笼形结构的AlPO-53（0.31×0.43 nm）和具有直孔型孔道的AlPO-5（0.73×0.73 nm）的甲烷储存量相当（1.54 mmol/g,273 K,2000 kPa）,均低于SAPO-34分子筛。结果表明,分子筛的笼型结构对其甲烷的储存量至关重要,具有最佳吸附孔径的微孔吸附剂,只有具有了笼型结构才可能具有好的甲烷储存能力;孔口小于甲烷动力学直径的有笼型结构的微孔吸附剂也能具有较大的甲烷储存能力。

| Abstract: | Aluminum-phosphate molecular sieves with regular porous structure posses the capacity of adsorption and methane storage.Previous research mainly concentrate on their storage capacity,while the report on relationship between their structure and capacity are quite rare.Methane storage capacity on AlPO-53,SAPO-34 and AlPO-5 at different temperatures(273K and 303K) and pressure 100-2000 kPa have been investigated,the relationship between their structure and capacity also analysed.Under the experiment conditions... |
