A method for carrying out a chemical reaction includes using a reactor arrangement in which reaction tubes arranged in a reactor vessel are heated to a reaction tube temperature level between 400° C. and 1,500° C. during a reaction period using radiant heat provided by means of one or more electric heating elements arranged in the reactor vessel. In at least a part of the reactor vessel in which the heating elements are provided, a gas atmosphere is provided during the reaction period, which gas atmosphere has a defined volume fraction of oxygen.
