Iron poisoning on catalyst has serious adverse effect on FCC performance including loss of catalyst activity and bottoms cracking ability.It has caused much attention since iron content in FCC feedstock is increased during processing acidic crude.Although there are several publications on addressing the effects of Fe poisoning on FCC catalysts via the analysis of E-cat samples,it is still not very clear why some catalysts can stand more iron content while some catalysts were influenced significantly by the increase of iron content on E-cat.
