摘要

Process for autothermally carrying out endothermic high temperature reactions comprises continuously introducing a reaction mixture having a low temperature to the front end of the reactor during the production phase, heating to a temperature necessary for the required conversion, cooling and removing from the reactor. In a regeneration phase, a regeneration stream is introduced at low temperature to the rear end of the reactor and withdrawn at the front end. The total heat capacity of the regeneration stream over a regeneration period of 30-300 %, preferably 80-120 %, corresponds to the total heat capacity of the reaction mixture over the course of the production.
