✦ Synopsis

Catalytic reactions that involve changes in the number of moles as reactants are converted into products, induce a two-dimensional velocity field that affects the nonisothermal reactor performance. The numerical solution of the governing equations for conversion. temperature, and the stream function show that the hot-spot temperature, reactor performance, and stability to temperature runaway depend strongly on the often neglected expansion coefficient for the chemical reaction. The results show that the effect can be accounted for, in all cases, by the variation in the mean axial velocity. REWORDS Two dimensional catalytic reactor, molar expansion, hot spot temperature, heat transfer,and velocity profiles.

## Abstract Three‐phase reactors involving a solid catalyst are normally used for production of product or removal of impurity. Equations are presented for these two measures of reactor performance for a first‐order, reversible or irreversible reaction in an isothermal reactor. The results are pres
