The invention relates to a method for a simultaneous production of methyl ethyl ketone and cyclohexane in the same reactor. The method is characterized by taking a mixture of sec-butyl alcohol and benzene (a mol ratio is controlled to be not lower than 4, preferably 4-10) as a raw material, vaporizing, treating by a two-stage catalytic reactor containing a nickel-copper catalyst, and rectifying and separating. Conditions of two stages of reactions are as follows: conditions of the first stage of reaction is as follows: reaction temperature is 150-250 DEG C, reaction pressure is not greater than 0.5MPa, the mol ratio of sec-butyl alcohol and benzene is not lower than 4, and the space velocity of the mixing material liquid is 0.5-2.5; and the conditions of the second stage of reaction is as follows: reaction temperature is 180-250 DEG C, and reaction pressure is not greater than 1.0MPa; and yields are respectively as follows: the yield of the cyclohexane is not lower than 98.5%, and the yield of ethyl ketone is not lower than 97.0%.
