部１２も不要となる。As described above, in the present invention, each of the catalytic reaction sections 5A to 5D incorporates a vertical cylindrical catalyst layer 1, and each supports 13.
Since the gas population 3 can be placed at the bottom of each catalyst reaction section 5A to 5D and the gas outlet 4 can be placed at the top, the gas flows radially to the catalyst layer 1. This can prevent drifting and improve gas diffusion. Furthermore, even if the catalyst layer 1 expands due to the heat of reaction, the temperature gradient in the catalytic reaction parts 5A to 5D is relatively gentle because the entire catalyst N1 is surrounded by gas, and the thermal stress is reduced accordingly. The members are simple, the number of columns 13 is extremely small compared to the conventional example shown in FIG. 4, and the strong lower structure 12 shown in FIG. 4 is not required.
