| Abstract: | MMC-2 catalyst, a new DCC catalyst for increasing propylene yield developed by Research Institute of Petroleum Processing has been applied in the 650kt/a DCCU located in Anqing Petrochemical Company. In comparison with the original used CRP-1 catalyst under same operating conditions with similar feedstocks, the statistical running result showed that the propylene content in LPG increased by about 5 percentage points, the propylene yield increased by about 2. 6 percentage points, the olefin content in cracked naphtha decreased by 4 -8 percentage points, the octane number and the quality of the cracked naphtha were somewhat increased and improved respectively, and the LPG plus liquid product yields were equivalent. |
