A fixing structure of a catalyst bed layer in an alkane dehydrogenation reactor comprises a reactor cylinder, supporting brick columns are arranged in the reactor cylinder, a material distributor is arranged on the supporting brick columns, and a catalyst layer located below the material distributor is further laid in the reactor cylinder. Refractory bricks are laid on the upper surface of the catalyst bed layer close to the inner wall of the reactor cylinder, the refractory bricks are laid in the circumferential direction to form an annular pressed brick layer, and a plurality of through holes penetrating in the height direction are formed in each refractory brick; steel plates are flatly laid at the intersection of the pressed brick layer and the inner wall, and the steel plates are sequentially welded and connected after being flatly laid in the circumferential direction to form an annular pressing plate layer. According to the utility model, the refractory bricks with high volume density are flatly laid o
