More Propylene in FCC Units

摘要

The demand for propylene has been increasing worldwide recently and consequently the propylene production from FCC units has also been attracting more attention. From the view point of catalysts, ZSM-5 additive brings an effective impact on propylene production and JGC C&C has developed an advanced ZSM-5 additive named "OCTUP-α". In addition, FCC catalyst itself should be properly designed to maximize the performance of ZSM-5 additive for more propylene production. This paper shows the advanced technology to maximize propylene yield by a combination of the ZSM-5 additive developed and the base catalyst named "LMV Catalyst".
