Provided is a reaction method capable of suppressing both a rise in a differential pressure at a reactor due to the inflow of a large amount of gas and a drop in the yield of a product. Also provided is a method capable of charging a granular filler into the clearances between the heat transfer plates of a plate type reactor. The reactor which can remove and add heat by exchanging heat with a catalytic layer that causes the fed raw gas to react, wherein a differential pressure at the reactor, which is determined from air at room temperature in the absence of the catalytic layer, is 50 Pa or less, and a plurality of reaction zones are formed in the catalytic layer due to the voidage of the catalytic layer that decreases with distance from the entrance toward the exit of the raw gas. In the plate type reactor, the filler is charged into the clearances from a charging position, at which the angle of repose of the filler, the distance taken in the axial direction of a heat transfer pipe from the charging position to the end of the charging section of the filler, and a value of 10 % of a designed height at the highest point of a filling layer satisfy specific relations. |
