Influence of feedstock characteristics on the enhanced production of propylene by ZSM-5 additives in the fluid catalytic cracking process
Keywords:
FCC, fuel, propylene, ZSM-5.
Abstract
The influence of feedstock properties on the enhanced production of propylene by ZSM-5 additives was evaluated for the RFCC unit (Residue Fluid Catalytic Cracking) of Dung Quat Refinery using a FCC-SIM simulation. The results showed that the ZSM-5 additive produced a superior performance with the light and paraffinic feedstock compared to the heavy, and aromatic feedstock in terms of enhancing propylene production at the lowest expense of gasoline. However, the later feedstock gave gasoline with higher octane ratings by using the ZSM-5 additive. Thus, based on the desired products, the operator could choose suitable feedstocks to maximise the ZSM-5 additive’s benefits.
