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 ...
Binder effect upon the catalytic behavior of PtCoZSM5 washcoated on cordierite monoliths
(Elsevier Science, 2004-11)
PtCoZSM5 in powder form is an effective catalyst for the selective reduction of NOx with methane. In order to attach a stable film of this powder to a cordierite honeycomb monolith, several approaches were assayed. Either ...
Development of a stacked wire-mesh structure for diesel soot combustion
(Elsevier, 2014-03)
This work describes the development of stacked wire-mesh structures and their washcoating method to prepare a structured system for the catalytic combustion of soot. For this purpose, a metallic structured substrate was ...
Obtaining stable suspensions for washcoating in microchannels: Study of the variables involved and their effects on the catalyst
(Elsevier Science SA, 2019-12)
La0.5Ca0.5CoO3-δ and La0.9Mg0.1Al0.9Ni0.1O3-δ perovskites were prepared for ethanol oxidation reaction and for ethanol steam reforming. The perovskites were mechanically ground and suspensions were subsequently prepared ...
n-butane dehydrogenation on PtSnIn and PtSnGa trimetallic catalysts supported on structured materials prepared by washcoating
(Elsevier Science, 2021-12)
The aim of this work was to evaluate PtSnIn and PtSnGa catalysts supported on structured materials, composed of a thin layer of γ- Al2O3 deposited on compact spheres of α-Al2O3, in the non-oxidative dehydrogenation of ...
Effect of the Pt/Co ratio upon the catalytic behavior of PtCoFerrierite washcoated on cordierite monoliths
(Elsevier Science, 2005-10)
CoFER and PtCoFER were prepared with different Co loadings and Co/Pt ratios. The resulting powders were washcoated on ceramic honeycombs. To increase adherence, silica was added to the slurry as a binder. The samples were ...
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 ...
Washcoated Pd/Al2O3 monoliths for the liquid phase hydrodechlorination of dioxinsMonolitos de Pd/Al2O3 washcoated para la hidrodecloración en fase líquida de dioxinas
(Applied Catalysis A: General, 2012)
The catalytic activity and durability of 2 wt.% Pd/Al2O3 in powder and washcoated on cordierite monoliths were examined for the liquid phase hydrodechlorination (LPHDC) of polychlorinated dibenzop-dioxins/polychlorinated ...
