Control Strategies Evaluation for a Three-Phase Hydrogenation Catalytic Reactor

Hydrogenation reactions are widely applied industrially, and reactors have been designed for this purpose. It is a highly non-linear process, multivariable, with exothermic reaction. The model formulation was made focusing on the hydrogenation reaction of o-cresol to obtain the 2-methil-cyclohexanol, in the presence of a Ni/SiO2 catalyst. A competitive advantage in such kind of system (a commod...

Modeling molecular transport in composite membranes with tubular fillers

Nanotubes have been shown to possess intriguing mass transport properties, and are being incorporated into polymeric membranes for molecular separations. Although models have been developed to predict the effective permeability and selectivity of composite membranes with non-spherical fillers, they only apply to fillers with isotropic transport properties. However, molecular transport in tubula...

Modeling Transport Phenomena in Selective Catalytic Reductant Catalytic Converter with NH3 as Reductant for NO Degradation

In the current study, reduction of nitrogen oxide from exhaust gas in the presence of NH3 as reductant on selective catalytic reductant (SCR) impregnated catalytic converter was simulated using Comsol© software. Mass transfer (one-dimensional) and heat transfer (three-dimensional) governing equations were taken into account to model the unsteady state behavior of the catalytic converter. Modeli...

Selective Catalytic Reduction of CuO/SiO2 Nano-composites towards NO Reduction in Gas-phase

The xerogel samples were prepared by hydrolysis and condensation of tetraethyl orthosilicate (TEOS) by the sol-gel method. In this investigation, a new molar ratio of H2O/TEOS was determined to be 11.7. Also, the necessary amounts of tri-hydrated copper nitrate and penta-hydrated copper sulfate were added to the solution in such a manner that the concentration of the copper oxide in final solut...

Tubular MFI Zeolite Membranes Made by In-Situ Crystallization

Polycrystalline MFI zeolite membranes were prepared on α-alumina tubular support by hydrothermal treatments at 413 K. The synthesized zeolite membranes were characterized by XRD, SEM and single gas permeation. The influence of hydrothermal treatment steps and the calcination time on the zeolite layer formation were investigated. MFI zeolite membrane prepared by four subsequent hydrothermal ...
