| Abstract: | On the basis of previous research work, an improved processing technology of two stage catalytic cracking was developed. This new technology has a feature of several fundamental modifications in reaction control mode for getting a better FCC product distribution and a higher yield of light oil. The experimental results show that the diesel oil yield with the new technology increased by 8 percentage point and the gasoline oil yield decreased by 7 percentage point while the dry gas yield and heavy oil yield decreased by 1 percentage point and 8 percentage point respectively at the similar feedstock conversion,comparing with the data obtained from the single stage FCC experiment. |
