摘要: 本文对直接法合成并经不同条件水蒸汽处理的HZSM-5分子筛进行了粉末X-射线衍射分析和红外光谱(IR)、程序升温脱附(TPD)的考察.结果表明:水蒸汽处理的温度、时间及环境中的水含量是影响HZSM-5结构和表面酸性的三个重要因素.对水蒸汽影响酸性变化的规律也进行了研究和讨论.

Abstract: The methods of X-ray diffraction, infrared spectrum and temperature-programmed desorption were used to investigate the properties of the zeolite HZSM-5, which was treated with super-heated steam. The effects of treatment temperature, time and content of water on the acidities of the samples were discussed emphatically.
