STUDY ON THE CONTROL TECHNIQUE OF HYDROGEN TRANSFER REACTION IN FCC

Hydrogen transfer reaction is one of the most important reaction in FCC. It determinates distribution of the product, quality of product and the olefin content in cracked product. Base on the mechanism and the character of thermodynamics and kinetics of hydrogen transfer reaction, control technique affecting hydrogen transfer reaction such as reaction temperature, catalyst/oil ratio, residence time, acidic structure of catalyst, Si - Al ratio, rare earth concentration were analyzed. It were in favour of decreasing the olefin content of gasoline.
