    Notes: Some characteristics are reported for the fluidization of an air-microspheroidal catalyst system in a 16-in.-diameter bed equipped with baffles. The back-mixing characteristics and retention-time distributions of gas and solids, allowable gas and solids velocities, entrainment rate, and bed density are studied as functions of baffle design.It is shown that the use of baffles narrows the retention-time spectrum and permits either concurrent or countercurrent flow while not seriously reducing gas or solids throughput or solids holdup.

    Notes: The reaction rate of gaseous acetylene and hydrogen chloride was studied experimentally on a mercuric chloride-activated carbon catalyst at pressures from 1 to 4 atm. and temperatures of 167°, 212°, and 257°F. The measurements were made in a differential reactor packed with mercuric chloride impregnated on activated carbon, the data being taken to obtain the separate effect of the partial pressure of each of the components on the rate.The results indicated that hydrogen chloride was strongly adsorbed on the catalyst and that vinyl chloride was also adsorbed to a significant extent. A rate equation, which well represented the data, was developed from the following postulates: (a) acetylene is adsorbed on the catalyst on one type of site, (b) hydrogen chloride and vinyl chloride are adsorbed on a different kind of site, (c) the formation of vinyl chloride occurs by reaction of adsorbed acetylene and adsorbed hydrogen chloride, and (d) the rates of adsorption and desorption are fast compared with the formation rate of vinyl chloride.

    Notes: An improved method is presented for handling isomer groups in the calculation of chemical equilibria in complex hydrocarbon mixtures. The new method reduces the number of simulataneous equations involved and makes practical the rigorous calculation of any hydrocarbon system for which free-energy data are available, no matter how complex.

    Notes: A theoretical analysis for turbulent flow of non-Newtonian fluids through smooth round tubes has been performed for the first time and has yielded a completely new concept of the attending relationship between the pressure loss and mean flow rate. In addition, the analysis has permitted the prediction of non-Newtonian turbulent velocity profiles, a topic on which the published literature is entirely silent.To confirm the theoretical analysis, experimental data were taken on both polymeric gels and solid-liquid suspensions under turbulent-flow conditions. Fluid systems with flow-behavior indexes between 0.3 and 1.0 were studied at Reynolds numbers as high as 36,000. All the fully turbulent experimental data supported the validity of the theoretical analysis. The final resistance-law correlation represents a generalization of von Karman's equation for Newtonian fluids in turbulent flow and is applicable to all non-Newtonians for which the shear rate depends only on shear stress, irrespective of rheological classification. All the turbulent experimental data for the non-Newtonian systems were correlated by this relationship with a mean deviation of 1.9%.

    Notes: Heat transfer and fluid dynamics were studied in columns in which hot mercury was sprayed into a rising stream of water. Volumetric and area heat transfer coefficients are presented which were found to be lower than those reported for heat transfer from fixed spheres.It was observed that considerable water bypassed the stream of drops, while some surrounding the drops flowed downward. This behavior resulted in water temperatures at the base of the column which were considerably higher than the inlet water temperatures. Consequently the outlet mercury temperature did not approach the inlet water temperature as a limit. The very unconventional flow pattern of the water was unexpected and is believed to be an important factor in spray-column heat transfer and mass transfer kinetics.

    Notes: The influence of high concentration gradients and high evaporative velocities on rates of mass transfer was studied by evaporating liquids into low-speed inert gas streams at pressures approaching the vapor pressure of the liquids.Inert gas concentration in some experiments changed nearly fivefold across the boundary layer. The velocity normal to the surface (owing to evaporation), usually neglected in comparison with main-stream velocity, varied from 0.038 to 19 times the main-stream velocity.The data for air-water, air-carbon tetrachloride, air-chlorobenzene, and helium-chlorobenzene systems were represented within experimental error over the Graetz number range of 0.1 to 1,800 by the flat-duct equations of Butler and Plewes (2) and also by the usual dimensionless plots.
