“…The rheological properties of the solutions were obtained with a Brookfield viscometer, Model LTV, and the data were fit to a power-law model. The power-law constants were evaluated by methods developed by Runikis et al (1958) and Sikdar and Ore (1979). The properties of the solutions used in this work are listed in Table I.…”

Mass transfer from spheres of benzoic acid to power-law fluids, consisting of aqueous solutions of carboxymethyl cellulose, was examined in the creeptng flow regime. The rate of transfer Increased with Peclet number, but it tended to vary by as much as a factor of 4 from theoretical predictions. The influence of fluid pseudoplasticity could not be determined possibly because of an increasing effect of natural convection on the transfer process as the continuous phase approached Newtonian behavior.A novel approach to the measurement of resldence time distributions (RTD) in chemical reactors is described. The technique involves the attenuation of neutrons by tracers and is particularly sukable for obtaining residence time measurements in coal hydrogenation reactors.
