丝光沸石/SAPO-34复合分子筛胺化催化剂及其制备方法
摘要：
本发明公开了一种丝光沸石/SAPO-34复合分子筛胺化催化剂及制备方法，制得的该催化剂的原料重量百分组成为：丝光沸石/SAPO-34复合分子筛：75%～90%，氧化钛：5%～15%，氧化铝粘结剂：5%～10%；原料重量百分数之和为100%；其中丝光沸石/SAPO-34复合分子筛中，SiO2/Al2O3为20～80的丝光沸石为复合分子筛总重量的50%～80%，SAPO-34分子筛为复合分子筛总重量的20%～60%。其制备方法是将铝源、磷源、硅源、模板剂混合后，再加入丝光沸石，置于高压釜中晶化后得到丝光沸石/SAPO-34复合分子筛，再将复合分子筛、氧化钛和氧化铝混合均匀，压制成型，在450℃焙烧8h，得胺化催化剂。
摘要（英）：

The invention discloses a mordenite/SAPO-34 composite molecular sieve amination catalyst and a method for preparing the same. The amination catalyst comprises the following raw materials by weight percent: 75-90% of mordenite/SAPO-34 composite molecular sieve, 5-15% of titanium oxide, and 5-10% of alumina binder. The mordenite with the ratio of SiO2 to Al2O3 being 20-80 in the mordenite/SAPO-34 composite molecular sieve accounts for 50-80% of the total weight of the mordenite/SAPO-3 composite molecular sieve, and the SAPO-34 molecular sieve accounts for 20-60% of the total weight of the mordenite/SAPO-3composite molecular sieve. The method for preparing the mordenite/SAPO-34 composite molecular sieve amination catalyst comprises the following steps of: mixing an aluminum source, a phosphorus source, a silicon source and a template agent, adding the mordenite, putting the materials in a high-pressure kettle, and crystallizing to obtain the mordenite/SAPO-34 composite molecular sieve, mixing the mordenite/SAPO-34 composite molecular sieve, the titanium oxide and the alumina uniformly, pressing and moulding, and sintering at 450 DEG C for 8 hours to obtain the amination catalyst.
