Abstract

In a fixed-bed flow reaction using a multitubular heat exchange type reactor, an object of the present invention is to provide a novel packing for a reaction tube, which can control the reaction ratio in the vicinity of the reaction tube inlet, reduce the load unevenly placed on the catalyst in the reaction region, and distribute the load on the entire catalyst layer, a heat exchange type reactor, and a reaction method using the reaction tube. The packing for a reaction tube of the present invention is characterized in that the volume is continuously or step-by-step decreased from one end part or midway toward the other end part.
