T he performances of the bifunctional additives to FCC catalyst was investigated on a FCC micro fixedbed reactor unit. Also, the uptake ability of SO2 was evaluated over the hydrothermal treated samples under the conditions similar to that of the FCC regenerator. T he results showed that the activity of thermal treated bifunctional additives was comparable to that of the commercial propylene additive LTB1 for increasing propylene yield. However, the activity of ZSM5 in the hydrothermal treated samples for increasing propylene yield was greatly reduced, due
