摘要： A coupled fluidized beds reactor-regenerator apparatus for catalytic dehydrogenation of propane. The fluidized bed reactor comprising a raw material delivery system, a pre-rising system, a reaction system, a gas-solid separation system and an internal circulation pipeline, the reaction system includes a conical riser and a turbulent bed reactor; the raw material delivery system, the pre-rising system, the conical riser, the turbulent bed reactor, and the gas-solid separation system are consecutively connected in this order from bottom to top; the bottom outlet of the gas-solid separation system is connected to the inlet of the internal circulation pipeline, and the outlet of the internal circulation pipeline is connected to the raw material delivery system and/or the reaction system. The coupled fluidized beds reactor-regenerator apparatus for catalytic dehydrogenation of propane includes the fluidized bed reactor, a gas-solid airlift loop regenerator, a recirculation inclined pipe and a regeneration inclined pipe.
