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

✦ Synopsis
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 determined if complete data on the kinetics of the reaction are available. This work is a continuation of a previous paper.

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
