Hydrogen from methanol-steam reforming. Isothermal and adiabatic monolith reactors' simulation
(Pergamon-Elsevier Science Ltd, 2008-07-04)
In this work a simple, precise and fast procedure to simulate monolith reactors where the methanol-steam reforming reaction is carried out is presented. The technique accounts for the interfacial heat and mass transport ...
Heat and mass transfer limitations in Monolith reactor simulation with non uniform washcoat thickness
(Planta Piloto de Ingeniería Química, 2010-01)
In this contribution, effectiveness factor (n) calculations are performed by a perturbation and matching technique developed by the authors which takes into account both the intrinsic kinetic expression and external heat ...
Simulation of CO Preferential Oxidation (COPrOx) Monolithic Reactors
(De Gruyter, 2014-01)
In this work, a COPrOx monolithic reactor with a CuO/CeO2/Al2O3 catalytic washcoat was modelled to purify a H2 stream for a 2 kW PEM fuel cell. Preliminary simulations included isothermal monoliths operating between 423 ...
Effectiveness factor calculation and monolith reactor simulation with non-uniform washcoat and arbitrary catalytic activity distribution
(Plapiqui, 2011-01)
A simple, precise and fast procedure to simulate monolith reactors is presented. The method allows the estimation of effectiveness factors (η) in monolith with washcoat of irregular geometries and arbitrary catalytic ...
Mathematical modeling of the partial hydrogenation of vegetable oil in a monolithic stirrer reactor
(John Wiley & Sons Inc, 2014-07-02)
Experimental and theoretical studies on the partial hydrogenation of vegetable oil in a monolithic stirrer reactor are reported. A complete mathematical model of the reactor was developed, including hydrogenation and ...
VOCs abatement in adiabatic monolithic reactors: Heat effects, transport limitations and design considerations
(Elsevier Science Sa, 2016-12)
A simulation study of a monolithic reactor for the catalytic oxidation of Volatile Organic Compounds (VOC) over a Mn-Cu mixed oxide catalyst is presented. A heterogeneous 1D mathematical model is selected to describe the ...
CO removal for hydrogen purification via Water Gas Shift and COPROX reactions with monolithic catalysts
(Elsevier, 2022-02)
A combination of Water Gas Shift (WGS) and CO preferential oxidation (COPROX) reactions is considered a promising approach for CO removal in an H2 feed employed for PEM fuel cells. Honeycomb monolithic catalysts were studied ...
