PROBLEM TO BE SOLVED: To provide an exhaust reformer system control device for an internal combustion engine, capable of improving the producing efficiency of reformed gas while suppressing the deterioration of a reforming catalyst due to caulking. SOLUTION: The exhaust reformer system control device comprises a recirculation passage 21 connecting an exhaust passage 3 to an intake passage 2 in the internal combustion engine 1, a reforming injector 22 arranged in the recirculation passage 21 for injecting alcohol mixed fuel containing alcohol in exhaust gas to be returned into the intake passage 2 via the recirculation passage 21, and the reforming catalyst 23 arranged in the recirculation passage 21 on the side of the intake passage 2 beyond the reforming injector 22 for reforming the alcohol mixed fuel in the exhaust gas EG into reformed gas RG containing hydrogen. Herein, an alcohol concentration detector 15 is provided for acquiring the concentration of alcohol in the alcohol mixed fuel. An ECU 30 adjusts the amount of the alcohol mixed fuel to be injected from the reforming injector 22 according to the concentration of alcohol acquired by the alcohol concentration detector 15.
