<p>A high temperature chemical reaction process is disclosed which is characterized by steps wherein an annular envelope of an inert fluid which is substantially transparent to radiation is generated, the envelope having substantial axial length and the interior of the envelope defining a reaction chamber. At least one reactant is passed through the reaction chamber along a predetermined path substantially coincident with the longitudinal axis of the envelope. High intensity radiant energy is generated at a point external to the reaction chamber and is collected, focused, and directed into the reaction chamber to coincide with at least a portion of the predetermined path of the reactants, sufficient radiant energy being absorbed within the reaction chamber to raise the temperature of the reactants to a level required to initiate and sustain the desired chemical reaction. This process can be utilized to carry out high temperature chemical reactions such as the dissociation of methane to obtain carbon black and hydrogen. Also disclosed is a reactor for carrying out said process, and which includes a reactor tube which is transparent to radiation, the tube having inner and outer walls between which is an annular chamber through which a coolant may be circulated, the inner wall defining the reaction chamber. The reactor also includes a diffuser through which the inert fluid is directed into the reaction chamber to form the above-mentioned annular envelope, means for introducing a reactant into the reaction chamber, and means for generating the high intensity radiant energy.</p> |
