摘要
综述了近年来分子筛催化材料在催化裂化生产燃料油改质技术中的应用。分子筛作为酸性催化材料,在燃料油改质、特别在降低催化裂化(FCC)汽油烯烃含量和硫含量等方面发挥了重要的作用。Y型分子筛和ZSM-5型分子筛是最基本的催化活性组元。分子筛的改性技术和新型结构分子筛的应用是燃料油改质技术的发展方向。
Application of molecular sieves in upgrading of FCC fuel was reviewed, As an acidic catalytic materials, molecular sieves or zeolites play an important role in upgrading of FCC fuel, especially in olefin reduction and desulfurization, Y and ZSM-5 zeolites are the basic catalytic components for FCC fuel upgrading. Modification of the molecular sieves and application of new structure molecular sieves are the trends in FCC fuel upgrading.
