Abstract: |
The reactions of olefins in FCC gasoline on FCC semi-regenerated catalysts with different coke contant after burning in oxygen, and the reactions under different reaction conditions such as temperature, the ratio of catalyst to oil and so on, were studied. The results show that using the catalyst with the temperature of 400 C,mass fraction of coke remaining less than 0.5%,the ratio of catalyst to oil as large as possible can effectively reduce the content of olefins, and keep high gasoline yield and the ideal composition of the upgraded gasoline. |
Key words: FCC gasoline olefin reduction yield |
