摘要
要提高催化裂化汽油辛烷值和深度加工渣油或重油,催化裂化催化剂是其关键。作为以上裂化催化剂活性组分的Y型分子筛的制备与改性更引起人们关注。Y型分子筛的改性,前人已作了大量研究,本文主要结合本课题组的工作,对几种分子筛改性方法进行较为系统的总结,以期探讨一些新的有更高工业化潜力的改性手段,为催化裂化生产用于MTBE等醚类高辛烷值汽油添加剂合成的低碳烯烃开发出催化剂的制备方法。
The innovation and development of the FCC catalysts are the key to increase the octane number of gasoline and be suitable for the deep processing of residuum or heavy oil. Of special interest is the synthesis and modification of the zeolite Y, which is the main active component of the above FCC catalysts. This thesis reviewed 17 references published in recent years to investigate the industrial potential methods of the synthesis and the modification of zeolite Y, which may be catalytically active for the production of the lighter olefins from feedstock of MTBE preparation.
