摘要
指出了目前重油催化裂化(RFCC)催化剂研究的核心在于减少重油分子在Y型分子筛中的扩散限制;研究方向主要集中在制备具有介-微孔结构的Y型分子筛和制备小晶粒Y型分子筛。分别介绍了介-微孔结构Y型分子筛和小晶粒Y型分子筛的优势、存在的问题以及制备的方法。最后提出了制备用于RFCC催化剂的新型Y型分子筛的发展趋势。
Reduction of diffusional limitation of heavy oil molecules in Y zeolite is focused on in recent years. The major research directions mainly include the preparation of Y zeolite with mesoporous-microporous structure and the preparation of small grain Y zeolite. The advantages,problems and preparation methods of mesoporous-microporous Y zeolite and small grain Y zeolite are discussed,respectively. Finally,the development trends of new type Y zeolite for RFCC catalyst are also suggested.
