Deep Catalytic Cracking (DCC) developed by RIPP (Research Institute of Petroleum Processing), SINOPEC is a catalytic conversion process derived from the FCC process using heavy feedstocks for producing raw materials used in the petrochemical industry, such as ethylene and propylene. It was firstly demonstrated in 1990 and has been commercialized since 1994. Up to now, seven units have been put into production inside and outside China, and many other DCC units are under construction and in the phase of design now. Products of propylene and ethylene from DCCU have been used as feedstock for manufacturing high quality polypropylene, polyethylene and acrylonitrile. Many innovations on technological process, and preparation of catalytic materials used in the DCC process will be presented in this paper.
