摘要： The present invention relates to a fluidized catalytic cracking process for cracking hydrocarbon feed having organo-sulfur compound as an impurity, said process comprising: adding a heavy metal poisoned spent catalyst to an equilibrium catalyst to obtain a composite circulating catalyst, wherein the heavy metal poisoned spent catalyst is added in an amount to maintain the activity of the circulating catalyst; and obtaining a fluidized catalytic cracked product.The present invention further relates to fluidized catalytic cracked product obtained by the process of the present invention. The sulfur content of the fluidized catalytic cracked product mainly gasoline which is boiling in the range of C5-250° C. reduced by more than 20% (wt/wt). And Research Octane number of the fluidized catalytic cracked product is increased by more than 1 unit.
