Abstract:
1. In an endothermic process that comprises contacting a hydrocarbon with a catalytic first component selected to produce a specified product mix in a catalyst bed in a fixed bed reactor, the improvement that comprises adding a heat-generating second component to the catalyst bed wherein said heat-generating component is selected so as to generate a predetermined amount of heat after being exposed to reducing reaction conditions or oxidizing reaction conditions or both reducing and oxidizing reaction conditions, wherein said heat-generating component does not promote coke formation or the formation of undesirable products under the optimal reaction conditions for the functioning of said catalytic first component, wherein said catalyst bed defines an inlet section and a middle section and an outlet section, wherein said catalytic first component is physically mixed with an inert component and loaded into said inlet section and said outlet section of said catalyst bed, and wherein said catalytic first component is physically mixed with said heat-generating second component and loaded into said middle section of said catalyst bed.
