摘要

Based on the reaction mechanisms and the characteristics of flexible dual-riser fluid catalytic cracking (FDFCC) process, the reaction networks of 10 lumps for heavy oil and seven lumps for gasoline were put forward. The cracking reactions of resin and asphaltene into gasoline and gases in heavy oil riser reactor were considered as second-order ones while the other reactions were described as first-order ones. The kinetic parameters indicate good consistence with the reaction rules of heavy oil catalytic cracking. The relative errors between calculated values and actual values of products are all less than 4%, which shows the reliability of the models.
