Study result suggest: The change of stock in RFCCU directly affect gasoline content. Gasoline content can be reduced through increasing the equilibrium activity of catalyst, controlling reaction level, increasing recirculating rate of gasoline and stability of gasoline level. Conclusions drawn from experiment is that optimization of operating condition has great effect on lowering olefine content of gasoline which can be reduced from 60% to 50%.Reducing reaction temperature is useful for lowering olefine content of gasoline, when the reaction temperature is raised, thermal cracking rate is higher than catalytic cracking rate, so that olefine content is increased. Raising catalyst-to-oil ratio is good for lowering olefine content. With conversion rate increased, the yield of LPG and coke is raised, the yield of gasoline is increased firstly and then decreased slightly, hydrogen transfer index is increased, so the olefine content is decreased.
