Diameter transformed fluidized bed reactor: fundamentals and practice

Abstract

The most striking characteristic of the fluidized bed reactor is the homogeneous state of temperature and catalyst density in the reactor, making it difficult to optimize the conversion and selectivity of complex catalytic reactions in different reaction zones. For two decades of continuous innovation, a concept of two different reaction zones was proposed to control the complex catalytic reactions, and the diameter transformed fluidized bed reactor with multi-flow in a single reactor was invented, based on which the pioneering catalytic reaction engineering technology platform was formed. On this platform, several catalytic reaction processes have been developed. The high efficiency processing technology for heavy hydrocarbons and the two-zone fluid catalytic cracking technology has been widely applied. The light olefins technologies being developed should be more competitive in petrochemical market in the future.
