AM-97-30 CONCLUSIONS OF ONE YEAR MI0 PROCESS COMMERCIAL PRACTICE

Description:

How to increase the production of reformulated gasoline (RFG) has been concerned by refiners of all countries in the world since 1990 Clean Air Act amendment promulgated in the United State. Nowadays the most urgent matter is to look for an economic and realistic route to greatly increase production of Iso-Olefins (IO) such as isobutylene and isoamylenes for oxygenates manufacture. A novel’ FCC process (MIO), aiming at maximizing isoolefins yield, has been developed and commercialized successfully by the Research Institute of Petroleum Processing (RIPP) / SINOPEC. In recent years, the development and evaluation of MI0 proprietary catalyst has been completed. Results of evaluation of the catalyst performance were presented in 1994 NPRA annual meeting [‘I and AlChE meeting t2]. In 1995, MI0 process was put into commercial trial. Satisfactory results was obtained t31, in which IO yield was 2.85 times of the FCC operation mode. The factors impact on IO yield and methods for further increase IO yield will be-discussed in this paper.
