Research and Development of Maximizing Iso-Paraffins (MIP) Technology

Research Institute of Petroleum Processing has successfully developed a maximizing iso paraffins (MIP) technology in response to the clean gasoline specifications. A concept of two different reaction zones technique was proposed based on the FCC reaction mechanism. The concept was used to design a novel reactor with the corresponding engineering measures. Results of experiments conducted on the newly designed pilot plant riser reactor showed that the formation of iso paraffins was enhanced by the two reaction zones technique; olefin content and sulfur content in gasoline were lowered simultaneously. The catalyst tailored for MIP process has also been developed and commercialized. An existed 1.4Mt/a RFCC unit was revamped to demonstrate MIP process, and the commercial trial results were in good agreement with the results of pilot plant test. MIP technology has provided a new approach for producing clean gasoline from heavy oil.
