Abstract A fluidized catalystic process for transforming hydrocarbons includes such steps as preheating hydrocarbons as raw material, fluidized catalytic transforming reaction in fluidized-bed reactor, quick separating of result to obtain oil gas, quick cooling the oil gas, fractionating in fractional tower to obtain transformed heavy oil, stripping the catalyst with coke, and regenerating the catalyst for reuse. It features that at least part of transformed heavy oil is directly or indirectly sprayed into dense-phase bed layer of stripping segment by symmetrically arranged nozzles.
