Oxidative coupling of methane on cordierite monoliths coated with Sr/La 2 O 3 catalysts. Influence of honeycomb structure and catalyst-cordierite chemical interactions on the catalytic behavior
(Elsevier Science, 2017-11)
When powder Sr/La2O3 catalysts are deposited on the walls of cordierite monoliths, an important increase in both, methane conversion and C2 yield, takes place. In this work, it is shown that this improved catalytic behavior ...
Zeolite washcoating onto cordierite honeycomb reactors for environmental applications
(Elsevier Science Sa, 2005-01)
The preparation conditions to obtain zeolite washcoats with optimum loading and homogeneous distribution are studied for mordenite, ferrierite and ZSM5, The slurry concentration and the number of immersions were combined ...
The effect of different slurry compositions and solvents upon the properties of ZSM5-washcoated cordierite honeycombs for the SCR of NO x with methane
(Elsevier Science, 2005-10)
ZSM5-washcoated monoliths were prepared using different slurry compositions and the following solvents: water, methyl alcohol, ethyl alcohol, isopropyl alcohol, butyl alcohol, ethyl acetate, and acetone. The effect of the ...
Oxidative coupling of methane on cordierite monoliths coated with Sr/ La2O3 catalysts. Influence of honeycomb structure and catalyst-cordierite chemical interactions on the catalytic behavior
(Elsevier Science, 2018-04)
When powder Sr/La2O3 catalysts are deposited on the walls of cordierite monoliths, an important increase inboth, methane conversion and C2 yield, takes place. In this work, it is shown that this improved catalytic behavioris ...
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 ...
Cobalt-Exchanged Mordenite onto a Cordierite Honeycomb for SCR-NO
(Taylor & Francis, 2008-04)
Structured catalysts were prepared by deposition of cobalt-exchanged mordenite films on the walls of cordierite monolith channels either by wash coating or by hydrothermal synthesis. The aim of this work is to analyze ...
Insights on the combustion mechanism of ethanol and n-hexane in honeycomb monolithic type catalysts: Influence of the amount and nature of Mn-Cu mixed oxide
(Elsevier, 2017-11)
Mn-Cu mixed oxides were deposited by ultrasonic impregnation on ceramic honeycomb monoliths. Its catalytic performance was evaluated in the combustion of ethanol and n-hexane, VOC molecules of different chemical nature. ...
Preparation, characterization, and application of nano-FeOx/Al2O3/cordierite monolithic catalysts for heterogeneous dark Fenton reaction
(John Wiley & Sons Ltd, 2020-11)
BACKGROUND: Advanced oxidation processes are an interesting alternative for wastewater treatment. The classic Fenton process, involving ferrous ions and hydrogen peroxide, requires strict pH adjustment and further iron ...
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 ...
