Abstract:

 COCR is a new process using fluidization technology to produce olefins from methanol and heavy olefins at a reaction temperature of about 570 ℃, a regeneration temperature of about 675 ℃ and an ethylene and propylene yield of over 35%. Relying on the mature fluidization process platform, COCR technology has high reliability. The coupling of exothermic and endothermic reactions of methanol and heavy olefin cracking can be achieved, and the heavy olefin resources can be comprehensively utilized. It has a wide application prospect.
