结果表明，由于磷促进了稀土离子由超笼向方钠石笼中的迁移，阻止了沸石在水热条件下的脱铝作用，从而改善了P RE USY沸石的水热稳定性；P RE USY沸石酸性分布更集中在中强酸范围，有利于发生氢转移反应，而强酸数量的降低有利于减少焦炭形成，改善了焦炭选择性。

An injection rate of 15μg/g CDF-10 antifoaming agent was normally injected to the top of the coke drum at the final 2-6 h of the coking cycle. It could eliminate 3m foam and increase the effective utilization ratio of the coke drum from 65%to 78%, and resulted in higher throughput. The said antifoaming agent had no poison effect on hydrogenation catalyst.

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.
