Abstract: Data of liquid yield from representative running MIP unit was analyzed and compared with FDFCC, FCC and TSRFCC processes. The statistical data show that MIP technologies have higher total liquid yields with higher gasoline and liquefied petroleum gas (LPG) yields, lower dry gas and slurry yields in processing hydrotreated heavy oil, hydrotreated gas oil and atmospheric residue. Relative to other technologies, the liquid yield of MIP is 2 percent higher at least with higher ratio of gasoline to diesel oil of MIP process. The MIP gasoline is lower in olefin and sulfur content and higher or equivalent octane number to other process. That can mainly attribute to the unique two reaction zones in one riser reactor, each having suitable reaction condition for the different reaction of hydrocarbons. The suitable reaction condition in each zone intensifies the heavy oil conversion and decreases dry gas and coke yields so that total liquid yield is increased.
