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...

A generalized nonlinear mathematical model for fixed-bed tubular chemical reactors with cooling is proposed. The model is suitable for simulation experiments. A strategy, focused on simplifying and adapting the "primary" model to control applications is shown. This procedure is driven through the so-called "pseudohomogeneous" form of the model until a final description which is linear and relat...
