<p>A process for carrying out an endothermic reaction in an endothermic reaction apparatus in which an endothermic reactant is heated by exothermic reaction of two fluids to thereby convert the reactant into an endothermic product, comprising causing the reactant to flow through a plurality of reaction tubes wherein the reactant is to undergo the endothermic reaction, the reaction tubes extending through an exothermic reaction chamber in laterally spaced apart relationship, separately supplying first and second exothermic reaction fluids to the exothermic reaction chamber for reacting within the chamber, the exothermic reaction products flowing in a direction going from an upstream end to a downstream end of the exothermic reaction chamber, the first fluid being introduced into the exothermic reaction chamber at the upstream end thereof in such a manner as to provide a substantially uniform velocity profile across the chamber, and the second fluid being introduced into the exothermic reaction chamber at or downstream of the first fluid and at a plurality of discrete locations interposed among but laterally offset from the reaction tubes, whereby the first fluid reacts with the second fluid for generation of high temperature flames around the reaction tubes and high temperature exothermic reaction products for flow around along the reaction tubes, for heating the reaction tubes to support an endothermic conversion of the endothermic reactant to the endothermic product as it flows through the reaction tubes. <IMAGE></p> |
