NOVELTY - Catalytic pyrolysis comprises contacting heavy material with catalyst containing chooser zeolite with average pore diameter smaller than 0.7 nm in first riser reactor including at least two reaction areas to carry out cracking reaction; contacting light material and cracked heavy oil with catalyst containing chooser zeolite in second riser reactor and fluid bed reactor to carry out cracking reaction; and leading hydrocarbon product to post product separation system to obtain cracking gas, cracking gasoline, cracking light oil and cracking heavy oil.    USE - Catalytic pyrolysis used for heavy oil.    ADVANTAGE - The method catalytic pyrolysis provides high conversion rate of heavy oil and yield of propene, while producing low yields for dry gas and coke.    DETAILED DESCRIPTION - Catalytic pyrolysis comprises contacting heavy material with cracking catalyst containing chooser zeolite with average pore diameter less than 0.7 nm in reaction area I of first riser reactor including at least two reaction areas; leading reactant to reaction area II to contact with cracking catalyst containing zeolite with average pore diameter smaller than 0.7 nm; separating oil and gas from accumulated carbon catalyst after reaction by separation device at outlet of reactor; further separating oil and gas by post product separation system to obtain cracking gas, cracking gasoline, cracking light oil and cracking heavy oil; contacting light material and cracked heavy oil with catalyst containing chooser zeolite with average pore diameter less than 0.7 nm in second riser reactor; leading to fluid bed reactor connecting with second riser reactor to continue reaction while leading cracking heavy oil to second riser reactor and/or bottom of fluid bed reactor; leading oil and gas from fluid bed reactor to depositor to separate solid; and leading hydrocarbon product to post product separation system to obtain cracking gas, cracking gasoline, cracking light oil and cracking heavy oil. The reaction in reaction area I is carried out at 500-700 degrees C for 0.4-10 seconds, and agent to oil ratio of 5-20. The reaction in reaction area II is carried out at 480-600 degrees C for 0.5-8 seconds, and agent/oil ratio of 7-20. The ratio of cracking catalyst led to reaction area I to cracking catalyst led to reaction area II is 1:(0.05-0.5). The heavy material is heavy hydrocarbon and/or different animal or plant oils rich in hydrocarbon. The light material is gasoline fraction and/or 4C hydrocarbon. The reaction in second riser reactor is carried out at 520-580 degrees C for 0.1-1.5 seconds, and agent/oil ratio of gasoline fraction of 10-30 when light material contains gasoline fraction; and agent/oil ratio of C4 hydrocarbon is 12-40 when light material contains C4 hydrocarbon and reaction time is 0.5-2 seconds. The reaction in fluid bed reactor is carried out at 500-580 degrees C, and at weight hourly space velocity of 1-35 hour. An INDEPENDENT CLAIM is included for catalytic pyrolysis device comprising first and second riser reactors, stripper, fluid bed reactor, depositor, product separation system, regenerator, and catalyst conveying line. The first riser reactor comprises equal-diameter rising tube, equal-line speed rising tube or diameter-changing riser reactor. The second riser reactor and fluid bed reactor comprise fixed fluid bed reactor, distributed fluid bed, bubble bed, turbulent bed, fast bed, conveying bed, or dense phase bed reactor.
