The lfexibility of MIP technology to meet market demand is mainly introduced in this study. Their commercial application and technical principle are analyzed too. The MIP technology with wide feed adaptability can form a good com-bination with other technologies. The MIP technology has been applied extensively in China. Based on this platform, the CGP, MIP-LTG and MIP-DCR technologies have been developed, which can further improve the lfexibility of MIP tech-nology. Based on its novel reaction control technique with a sole sequential two-zone riser, the MIP users can easily switch to different operating modes between producing either more clean gasoline and propylene or diesel through changing the catalysts and varying the operating conditions. That offers MIP users with enough production lfexibility and a rational pro-duction arrangement to meet the market demand. The MIP-DCR technology with less dry gas and coke yields can provide a more lfexible operating mode since the catalysts to oil ratio has become an independent variable.
