Abstract
Provided is a reactor that is capable of suppressing deformation and damage of catalyst grains due to contraction of a reaction tube after thermal expansion thereof. A reactor includes: a reaction tube A aligned in an up-down direction and having, in a bottom section thereof, a catalyst supporter receiving packed catalyst grains and allowing a processed gas to flow therethrough; and a burning unit configured to heat an outer face of the reaction tube A. The reaction tube A has a cylindrical catalyst support face U that is in contact with the catalyst grains in the reaction tube A and that have, in the up-down direction, a plurality of engaging recesses each capable of receiving a portion of the catalyst grain in contact with the catalyst support face in such a manner that the portion of the catalyst grain is fitted into the engaging recess.
