The rapid development trend of China ethylene industry in the recent years was introduced. Most of the light olefine were produced by the steam cracking in the worldwide. The steam cracking technology was extremely limited by the growing heavy low - quality and inferior quality trends of crude oil. Recent domestic and foreign catalytic pyrolysis technologies of the feedstock at the range of light hydrocarbon to heavy oil were reviewed. The representative technologies of deep catalytic cracking, catalytic pyrolysis process and heavy - oil contact cracking were introduced with emphasis. Heavy oil catalytic cracking was more suitable to our national condition. As of novel and effective catalyst matching with the technologies, the relationship between catalyst acid strength, nent and the catalytic pyrolysis activity was found out, which laid alytic pyrolysis technologies. pore distribution, the content of metal and active compo- a firmer foundation for the overall industrialization of cat-
