Advances in DCC Process and Catalyst for Propylene Production from Heavy Oils

  • Received:2010-11-05 Revised:1900-01-01 Online:2011-03-31

摘要: In the past several decades, SINOPEC has devoted continuously to develop DCC technology, the only commercial process using heavy feeds aiming at propylene production. Recently, a series of research breakthrough have been achieved in molecular refining. Based on the detailed analysis in the complex DCC reaction network, an innovative catalyst technology has been developed to Optimize Catalysis Kinetics (OCK in brief). The deep-cracking improve with optimizing the availability of the active sites. The updated MFI and beta zeolites are used to boost the propylene selectivity. The latest generation catalyst DMMC-1 has been applied commercially. Comparing with the best history, Propylene yield of DMMC-1 increases 2.4m%, distribution of products improve. The leading position of DCC has been advanced further.
