Abstract
A vertical, cylindrical reaction vessel for catalytic, exothermic gas-phase reaction in which gaseous raw materials are passed substantially in the radial direction through a catalyst layer including therein cooling tubes extended vertically. A cooling medium is passed through the cooling tubes to remove the heat of reaction generated thereby attaining the optimum temperature distribution along the direction of flow of the gaseous raw materials.
