Abstract
Threeβphase 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 firstβorder, reversible or irreversible reaction in an isothermal reactor. The results are presented in terms of dimensionless groups of the pertinent mass transfer, kinetic, and equilibrium (solubility) properties, and the gas and liquid flow rates. From the equations given, it is possible to predict the relative performance of concurrent (trickle bed) and countercurrent flow reactors and also the effect of mixing in the gas or liquid streams on performance.

Most existing criteria for predicting the critical residence time (or jlow rate) at which runaway occurs in an adiabatic catalytic packed-bed reactor do not account for interphase heat-transfer resistance and intraparticle diffusion. When these transport limitations exist, the critical residence tim
