改性NaY分子筛及其制备方法和应用以及加氢处理催化剂用载体和应用
摘要：
本发明公开了一种改性NaY分子筛及其制备方法和应用以及含有该改性NaY分子筛的加氢处理催化剂用载体和应用，改性NaY分子筛的制备方法包括：将NaY分子筛与有机酸在含水溶剂中接触，得到改性NaY分子筛，其中，所述改性NaY分子筛的孔道口的形状为喇叭状。根据本发明的方法得到的改性NaY分子筛，由于其孔道口为喇叭口状，减少了堵塞的几率，从而提高了催化剂的活性并且延长了催化剂的使用寿命。由此可见，本发明的改性NaY分子筛具有很好的工业应用前景。
摘要（英）：

The invention discloses a modified NaY molecular sieve, a preparation method and an application thereof, a carrier for a hydrotreatment catalyst containing the modified NaY molecular sieve, and an application of the carrier. The preparation method of the modified NaY molecular sieve is characterized in that the NaY molecular sieve is in contact with an organic acid in a water-containing solvent to obtain the modified NaY molecular sieve, and the duct mouth of the modified NaY molecular sieve has a trumpet-shaped shape. The trumpet-shaped shape of the duct mouth of the modified NaY molecular sieve obtained through the method reduces the obstruction probability in order to improve the activity of the catalyst and prolong the service life of the catalyst. The modified NaY molecular sieve has very good industrial application prospect.
