Disclosed are a catalytic cracking method and an apparatus for implementing the method. The catalytic cracking is carried out in a primary reactor and a secondary light material reactor, wherein in a first reaction region of the primary reactor, a regenerated catalyst contacts and reacts with a raw oil, the reaction mixture flows upward, and the catalyst is separated out by a separator; the separated catalyst flows to a stripping section, and the reacted oil gas flows upward along a delivery pipe and enters a second reaction region of the primary reactor; the catalyst to be regenerated from the secondary light material reactor enters the second reaction region of the primary reactor, and is mixed with the reacted oil gas from the first reaction region for further reaction; after the completion of the reaction, the oil gas is separated from the catalyst, and fed to a subsequent fractionation system, and the catalyst flows to the stripping section, is stripped together with the catalyst separated by the separator in the first reaction region, and enters a regenerator for regeneration. By using the apparatus and method disclosed herein, the production distribution and production quality are improved, the project investment is reduced, the energy consumption is lowered, and the implementation of the project is convenient. |
