超稳Y沸石由于其骨架结构具有很高的热稳定性、水热稳定性、化学稳定性而引起了人们的重视。它作为催化剂的一个重要组分(或催化剂载体)已用于催化裂化和催化加氢裂化。许多作者研究过超稳Y沸石的红外光谱。Ward比较了HY沸石和超稳Y沸石羟基伸振区的红外光谱,Jacobs和Uytterhoeven研究了深层焙烧NH_4Y产物的红外光谱,Scherzer和Bass详细研究了超稳Y沸石羟基伸振区和骨架振动区的红外光谱以及阳离子交换超稳Y沸石的红外光谱。
Ultra-stable Y zeolite has attracted people’s attention due to its high thermal stability, hydrothermal stability and chemical stability. It has been used as a catalyst for an important component (or catalyst support) for catalytic cracking and catalytic hydrocracking. Many authors have studied the infrared spectra of ultrastable Y zeolites. Ward compared infrared spectra of the HY stretching zone of HY zeolite and ultrastable Y zeolite. Jacobs and Uytterhoeven studied the IR spectra of the NH_4Y products by deep calcination. Scherzer and Bass studied in detail the hydroxyl stretching and vibrational regions of the ultrastable Y zeolite Infrared spectroscopy and cation exchange of ultrastable Y zeolite IR spectra.
