Abstract

Method and a reactor for performing exothermic catalytic reactions. The method comprises the steps of providing a feed gas stream comprising reactants for the exothermic catalytic reaction to a fixed bed catalytic reactor comprising one or more catalyst beds each with catalyst particles filled sections with a catalyst volume; providing a feed gas bypass inside the reactor by arranging within at least one of the catalyst beds a number of bypass passageways without catalytic active particles inside the passageways and having a cooling surface area; passing a part of the feed gas stream through the bypass passageways and reminder of the stream through the catalyst particles filled sections; and removing heat from the feed gas stream being passed through the catalyst filled sections by indirect heat transfer to the part of the feed gas stream being passed through the bypass passageways.
