Effects of hydrogen transfer reaction on the olefin content of gasoline in FCC process

Using fixed fluidized bed reactor, the effects of hydrogen transfer reaction on the olefin content of gasoline in FCC process were investigated. The experimental results show that the high activity and special olefin reduced catalyst, high ratio of catalyst to oil and long residence time are in favor of enhancing hydrogen transfer reaction and increasing hydrogen transfer reaction index. Only appropriate operation conditions such as reaction temperature, high C/O and long residence time can reduce the olefin content of gasoline.
