Abstract A catalytic cracking process for heavy petroleum hydrocarbon includes such steps as cooling the regenerated cracking catalytic in heat balance regulator, introducing it to 4-segment serial reactor, reating with preheated heavy hydrocarbon at 500-550 deg.C and 130-350 Kpa for 1-4 seconds, stripping the catalyst to be generated, regenerating, cooling and returning in back to reactor for cyclic use. Its advantages are high output rate of light oil (up to 65-68 wt.%), and high output rate of total hydrocarbon liquid (up to 80-84 wt.% or higher).
