Deep Catalytic Cracking Technology Bridging Petroleum Processing with Chemical Industry
Li Zaiting
Strategic Study of CAE 1999, Volume 1, Issue 2, Pages 67-71
Deep catalytic cracking (DCC) is a novel technology for producing basic organic raw material, especially propylene, from heavy oil. Research Institute of Petroleum Processing, SINOPEC developed the process and catalyst, and a commercial demonstration was successfully completed in 1990 at Jinan Refinery, China. Up to now, 7 units have been constructed and put into production worldwide. The low carbon olefins produced have been further synthesized to high quality polypropylene, polyethylene, acrylonitrile and other chemicals. Currently, the feedstock has been extended to atmospheric residue and tailor-made catalysts are available. The commercial experience of the first DCC plant outside China, TPI DCC in Thailand, is presented.
