Claims

[Scope of utility model registration request]

A reactor having a fluid inlet and an outlet at the upper and lower parts of the reactor, respectively, and a plurality of reaction tubes installed vertically inside the reactor with a diameter smaller than the diameter of the reactor and open at the top. In order to efficiently discharge debris or powder mixed into the catalyst layer, it is composed of a plurality of vertical slits in which adjacent rods are arranged at a predetermined pitch but widen toward the bottom, or a horizontal slit made up of multistage rings, or a wire mesh. What is claimed is: 1. A catalyst-filled reaction device comprising a conical catalyst supporting device, which forms a conical cage and has a tilt angle larger than the angle of repose of the catalyst particles, at the lower part of the reaction tube.
