Effect of radial velocity profiles on axial dispersion in packed beds: asymptotic behaviour
(Brazilian Society of Chemical Engineering, 2021-09)
Axial dispersion of a solute in a flow through packed beds arises from molecular diffusion, velocity variations at the interstitial-pore scale and systematic radial velocity profiles. Currently, there is not a widely ...

Prediction of the fixed-bed reactor behaviour using dispersion and plug-flow models with different kinetics for immobilised enzyme
(Elsevier Science Sa, 2003-05)
The behaviour of fixed-bed reactors, which have an immobilised enzyme on the packing surface, was studied considering steady-state conditions and external mass transfer resistance in the fluid around catalyst spherical ...

Dentro del espíritu investigativo a nivel teórico del estudio de los reactores químicos, el presente trabajo desarrolla e implementa un análisis conceptual y numérico de los fenómenos de dispersión axial de calor y masa ...
Supercritical CO2 processing of pretreated rosehip seeds: effect of process scale on oil extraction kinetics
(ELSEVIER SCIENCE BV, 2004)
Rosehip oil was extracted from milled seeds with supercritical carbon dioxide (SC-CO2). The effects of sample pretreatment and interstitial solvent velocity (0.40-2.45 mm/s) on kinetics of extraction (oil yield versus time) ...
