Wall-to-bed (or wall-to-fluid) heat transfer issues in trickle bed reactors (TBR) has an important impact on operation and efficiency in this category of reactors. In this study, the hydrodynamic and thermal behavior of trickle bed reactors was simulated by means of computational fluid dynamics (CFD) technique. The multiphase behavior of trickle bed reactor was studied by the implementation of ...

Studies on bench scale reactors packed with two different media matrix – Biopac media and Fugino spirals were undertaken to determine the performance at various organic loading rate (OLR) and on one day hydraulic retention time (HRT). Parboiled rice mill wastewater depicted a COD/BOD ratio of 1.6 indicating good degradable nature of the wastewater. Four different organic loadings of 0.8, 1.6, 2...

The development of tools for the synthesis, design, and optimization biorefineries requires deep knowledge thermochemical processes involved in these schemes. For this project, three models from scientific literature were implemented to simulate processes: fast pyrolysis a fluidized bed, fixed-bed, fluidized-bed gasification using Aspen PlusTM software. These allow user obtain performance, cons...

Carbon nanofibers have been immobilized onto carbon felt as the first step for their industrial application in Oxidative DeHydrogenation (ODH) reactions, exhibiting a stable performance with a high selectivity to styrene in the ODH of ethyl benzene at temperatures around 300 K lower than the actual industrial process, and inhibiting the problem that loose small particle as CNFs shows for being ...

Fluid dispersion in small fixed bed reactors under single phase laminar flow conditions is evaluated through accurate predictions of axial Péclet numbers Peax using Direct Numerical Simulations (DNS). The packing obtained the Discrete Element Method (DEM) code Grains3D. are computed from steady state simulations flow. An additional set equations solving spatial distribution moments age used. Th...
