Abstract
Abstract A high temperature reactor comprises a tube which defines a reactor chamber; means for introducing the inert fluid into the reactor tube to provide a protective blanket for the inside surface of the tube; means for introducing reactants into the chamber, the reactants being confined centrally within the chamber by the protective blanket; and, means for generating high intensity radiant energy which is directed into the chamber to coincide with at least a portion of the path of the reactants.
