7. An apparatus for controlling a reactor in a reformer, comprising:
a first prediction unit configured to predict properties of feed being currently supplied to a reactor set in real time by using a pre-trained first prediction model when a current operating condition of the reactor set in the reformer is input;
a second prediction unit configured to predict properties of products being produced in the reactor set in real time by using a pre-trained second prediction model when the current operating condition and the predicted properties of feed are input; and
a control signal generation unit configured to calculate a amount of temperature fluctuation to be applied to each reactor as a control signal for controlling each of the reactors of the reactor set based on the predicted properties of products,
wherein the operating temperature of each of the reactors is controlled based on the calculated amount of temperature fluctuation.
