Abstract

The invention relates to a process for the production of ethylene oxide from a gaseous feedstock--in a cooled exothermic catalytic reaction of ethylene and oxygen from this feed gas in parallel flow-through reaction zones. According to the invention, the reaction zones are limited by cooled dividing walls, and the cooling is achieved by a fluid that flows inside the dividing walls. In addition, the invention relates to a reactor for this purpose with catalyst particles between cooled dividing walls. According to the invention, the cooled dividing walls are formed with the aid of metal plates, and cavities in the form of channels for receiving and for passing through a coolant are arranged for cooling in the metal plates.
