Beschreibung
Zusammenfassung:	The invention provides a catalytic cracking apparatus and a catalytic cracking method for increasing yield of ethene and/or propylene using the apparatus. The apparatus comprises a lifting pipe, a gas and solid separator, a regenerator and a vertical pipe for agent to be regenerated. A discharge end of the lifting pipe and a feed inlet of the gas-solid separator are communicated; the lifting pipe comprises a first lifting pipe which crosses the inner part of the regenerator and is arranged parallel to the vertical pipe for agent to be regenerated, and the gas phase circulation outlet of the gas-solid separator is used for communicating with the gas-solid separator of the subsequent oil gas separating system, and the outlet of the agent to be regenerated and the vertical pipe for agent to be regenerated are directly contacted and communicated, thereby providing agent to be regenerated for the regenerator, and the discharge port of the agent to be regenerated in the regenerator is communicated with the feed inl
