PROBLEM TO BE SOLVED: To maintain a good fluidity in a fluidized bed catalyst reaction device, and prepare an aimed reaction product efficiently. SOLUTION: A catalyst fluidized in a fluidized bed reaction section is extracted, introduced into a cyclone and crushed. A catalytic active component is rendered the molten liquid state at the time of reaction. The device is provided with a reactor 5, a cyclone 2 attached to the reactor 5, a transfer piping 3 for transferring a catalyst from a fluidized bed reaction section 1 to the cyclone 2 having one end connected with the fluidized bed reaction section 1 in the reactor 5, and the other end opened on a gas suction area 6 of the cyclone 2 or connected with the cyclone 2, a gas introduction opening 4 for transferring the catalyst installed on a piping line of the piping 3 and a catalyst return piping 7 for returning the catalyst crushed and classified in the cyclone 2 to the fluidized bed reaction section 1. |
