Liquid phase systems during diffusion

Batch reactors are not common in experimental catalysis since flow systems are so simple. They are most often found with liquid phase reactors using slurried catalysts. Good mixing is essential and checks should be made to eliminate external diffusion problems. Also it is necessary to vary catalyst loading during the experiment as a means of detecting vapor-liquid interfacial effects. ... [Pg.183]

It was established flieoretically (97, 133) that when the surfactant is dissolved in the drop phase (System II in Fig. 15) it remains uniformly distributed throughout the drop surface during film thinning, and interfacial tension gradients do not appear. This is the result of a powerful supply of surfactant, which is driven by convective diffusion from the bulk of the drops toward their surfaces. For that reason, the drainage of the film surfaces is not opposed by surface-tension gradients, and the rate of film thinning, Fjj, is the same as in the case of pure liquid phases (97, 133) ... [Pg.643]
