摘要： 以有机胺或季胺盐作为模板剂,用水热法合成了AlPO4-5,AlPO4-11及AlPO4-20分子筛。所得样品用X-射线衍射图及红外先谱图进行表征。差热分析表明这些样品直到～950℃无结构破坏,所测样品的吸附等温线表明在AlPO4-5及AlPO4-11上水的吸附容量大于碳氢化合物。

Abstract: The AlPO4-5, AlPO4-11 and AlPO4-20 molecular sieves have been synthesized hydrothermally in the presence of organic amines or quaternary ammowum which acts as templcte. These samples were characterized by X-ray diffraction patterns and infrared spectra. It was found that the framework topology of AlPO4-11 is changed after calcinations. DTAshows no structural collapse below -950℃.The adsorption properties of water and hydrocarbons on the samples were studied. The results show that the water pore volumes are greater than the hydrocarbon pore volumes, reflecting the presence of additional pore volume accessible to H2Obut not to hydrocarbons.
