In this paper extensive numerical calculations for the schematic reaction system A + B + C are described in which the successive reactions may be of either first or second orders or both. From these computations the optimum temperature profiles and maximum yield of B for a given process time may be

✦ Synopsis
In this paper the mathematical techniques necessary for the determination of the optimum temperatures profile in a tubular reactor to insure maximum yields or minimum contact times are developed, and applications arc made to reversible and consecutive reaction * The authors are indebted to K. C. DENBIOH, who introduced them to these problems while he was a Visiting Professor in the Chemical Engineering Department at the University of Minnesota in 195844.

The method of dynamic programming ia used to solve the general problem of finding the temperature gradient in a tubular reactor, which will maximize some function expressing the profit made by the reaction. As an introductory example the reaction A + B + C when the yield of B is to be maximized is c
In tubular reactors (or in stirred reactors in series) it is possible to have the conditions vary along the tube. In this way better results can often be obtained. The effect of a pressure gradient is of interest in equilibrium gas reactions where the number of moles increases (e.g. &hydrogenation r
By considering the well known problem of determining optimum temperature profiles for the successive first order reactions 1 B AiBiC carried out in a tubular reactor it is shown that the application of Pontryagin's Maximum Principle is not straightforward, even in a case as simple as this. In partic
