“…The axial dispersion coefficient is at most proportional to the interstitial gas velocity (Edwards and Richardson, 1968;Suzuki and Smith, 1972), so at high values of U,, the axial dispersion term is negligible. Thus, the micropore diffusion coefficient can be obtained from the intercept of plots of dU0/2L vs. l/U: (referred to as variance plots).…”

“…the semi-empirical correlation proposed by Edwards and Richardson (1968) was used to estimate the axial dispersion coe$cient D X . The catalyst e!ectiveness factor, G , was set as unity for the crushed catalyst used in this work; see Section 4 for details.…”

An X-ray technique has been developed to determine the concentration and liquid holdup in a packed bed. To quantify these parameters in single and multiphase flow systems, at local level, a calibration method/graph has been developed. This graph has also been used to obtain the local concentration value of a liquid in presence/absence of another miscible liquid in a porous media. The same graph has been used to quantify the local liquid holdups (static and dynamic) in a packed bed. The same technique can be used for other radiological methods such as gamma rays and neutron radiography. Results obtained from this technique are in agreement with the published data.
