The invention relates to a process for hydrogenating silicon tetrachloride in a reactor, wherein a reactant gas containing hydrogen and silicon tetrachloride is heated to a temperature between 850&#xb0; C. and 1600&#xb0; C. by means of at least one heating element, which comprises a graphite surface, wherein the temperature of the heating element is between 850&#xb0; C. and 1600&#xb0; C. The process is characterized in that a nitrogen compound is added to the reactant gas in a substance amount fraction of 0.1 to 10% based on hydrogen.

The invention provides a process for endothermic gas phase reaction in a reactor, in which reactant gases are introduced into the reactor via a gas inlet apparatus and distributed homogeneously into a heating zone by means of a gas distribution apparatus, wherein the reactant gases are heated in the heating zone to a mean temperature of 500-1500&#xb0; C. by means of heating elements and then conducted into a reaction zone, the reactant gases reacting in the reaction zone to give a product gas which is conducted out of the reactor via a gas outlet apparatus. Further subject matter of the invention relates to a process for endothermic gas phase reaction in a reactor, wherein the heating of the heating elements is controlled by temperature measurements in the reaction zone, at least two temperature sensors being present in the reaction zone for this purpose, and reactor for performance of the process.
