<p>A reaction device provided with a reaction vessel, a solid-catalyst fluidized bed inside said reaction vessel, a cooling unit disposed inside the reaction vessel, a feedstock-gas introduction unit, and a gas-solid separation device laid out so as to: make a reaction gas that contains solid catalyst spewed upwards from the fluidized bed flow in through a gas inflow port that opens to the interior of the reaction vessel; separate out said solid catalyst from the reaction gas and collect said solid catalyst; and discharge, from a reaction-gas discharge part, the reaction gas that has been separated from the aforementioned solid catalyst. The gas-solid separation device is laid out so as to surround the centerline of the reaction vessel, and the gas inflow port in the gas-solid separation device is positioned so as to open towards the inside of the region surrounded by the gas-solid separation device.</p> |
