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 ...
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 ...
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 ...
Mass transfer limitations in a monolithic reactor for the catalytic oxidation of ethanol
(Elsevier, 2015-12)
A theoretical study of a monolithic reactor for the catalytic oxidation of Volatile Organic Compounds (VOC) over manganese–copper mixed oxide catalysts is presented. An isothermal one-dimensional heterogeneous model is ...
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 ...
Monolithic reactors for environmental applications: A review on preparation technologies
(Elsevier Science Sa, 2005-05)
The main aspects of preparation technologies for the manufacture of environmental monolithic catalysts have been reviewed on the basis of the patent literature, the authors' own experience in their laboratories, and the ...
Effect of heat losses on monolithic reactors for VOC abatement
(Elsevier Science Sa, 2019-12)
In this contribution a theoretical study of the thermal effects due to heat losses on monolithic reactors for the catalytic combustion of VOC is carried out. To describe the performance of the reactor under steady-state ...
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 ...
Monolithic stirrer reactor for vegetable oil hydrogenation: A technical and economic assessment
(Elsevier Science Sa, 2018-10)
The monolithic stirrer reactor (MSR) which consists on monolithic structures mounted on reactor axis as agitator blades is a novel design with the potential to intensify different production processes. Its most outstanding ...
