近年来,高铝硅铝不仅作为一个裂化催化剂开始应用于石油加工;而且,作为一个金属酸性催化剂的担体,无论在石油工业或化学工业上的地位也日益重要。但是迄今为止,对高铝硅铝的知识仅有初步了解,对其某些特性(如酸性,稳定性等)的了解则更为有限。这就使硅铝的制备与应用,及进一步改善共性质有一定的困难。因此我们对混合法高铝硅铝的酸性和稳定性进行了一 In recent years, not only has high aluminosilicate been used as a cracking catalyst in petroleum processing; moreover, as a support for metallic acid catalysts, it has become increasingly important, both in the oil industry and in the chemical industry. However, to date, knowledge of Al-Al-Si has only been initially known, and knowledge of some of its properties (such as acidity, stability, etc.) is more limited. This makes the preparation and application of Si-Al, and to further improve the common properties have some difficulties. Therefore, we conducted a mixed-acid high-aluminum silicon aluminum acid and stability of a
