将重质油轻质化生产符合环保要求的产品是当今炼油面临的形势和任务。催化裂化是炼油的主要工艺，近年及今后一段时期的发展趋势是加工更多的渣油，生产高辛烷值汽油组分，催化剂起着决定性的作用。５０年来的实践和科学研究，目前催化剂的领域已基本可以做到＂量体裁衣＂，并有很大空间留待开拓。 Lightweight production of heavy oil to meet the environmental requirements of the product is the current situation and tasks facing oil refining. Catalytic cracking is the main process of oil refining. In recent years and in the future, the development trend is to process more residual oil, and to produce high-octane gasoline components, the catalyst plays a decisive role. In the past 50 years of practice and scientific research, the field of catalysts has basically been “tailored” and there is plenty of room for development.
