PLATE TYPE CATALYTIC REACTION OVEN

摘要

A plate type catalytic reaction oven allowing the increase of a reaction performance and the extension of catalyst life by efficiently controlling a temperature distribution in a catalyst layer, characterized in that a plurality of pairs of heat transfer plates each formed of two sheets of corrugated plates joined to each other and each having a plurality of heat medium flow passages are arranged, the corrugated plate projected surface parts and recessed surface parts of the heat transfer plates adjacent to each other are opposed to each other to form the catalyst layer and, particularly, a circular or elliptic arc shape formed in the corrugated plates is changed to gradually increase the thickness of the catalyst layer from the inlet toward the outlet of reaction raw material gas fed to the catalyst layer.
