Effect of Ag-Co interactions in the mordenite on the NO x SCR with butane and toluene
(Elsevier Science, 2012-11)
A study of the lean NO x reduction activity with butane and toluene in the presence of water over bimetallic and monometallic Ag, Co exchanged on Na-mordenite catalysts was performed. The Ag-Co interactions were analyzed ...
Sleep Clinical Record application in Brazilian children and its comparison with Italian children
(2019-12-01)
Objective: To apply the Sleep Clinical Record (SCR) to a sample of Brazilian children with sleep complaints, to compare the results with Italian children, and to identify variables that influence phenotype. Methods: Brazilian ...
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 ...
The SCR of NO with methane over In,H- and Co,In,H-ZSM-5 catalysts: The promotional effect of cobalt
(Elsevier Science, 2012-05)
Zeolite In,H-, Co,H-, and Co,In,H-ZSM-5 were characterized by operando diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS), temperature-programmed reduction by hydrogen (H2-TPR), X-ray photoelectron ...
In,Fe-Zeolites: active and stable catalysts for the SCR of NOx. Kinetics, characterization and deactivation studies
(Elsevier Science, 2008-12)
In this work, the addition of Fe2O3 to InH-zeolites (ZSM5 and mordenite) is investigated for the selective catalytic reduction of NOx with both methane and butane as reducing agents. When Fe is added to InHMOR and methane ...
Effect of the location of cobalt species on NO adsorption and NOx-SCR over Co-mordenite
(Elsevier Science, 2007-03)
A thorough characterization of Co-mordenite was carried out using NO-TPD, H2-TPR, Raman, DRX and FTIR with NO as probe molecule. Different cobalt-loading catalysts (8.85, 5.70, 2.91, 2.45 and 1.15 wt.%) were prepared by ...
Cobalt Supported on Zirconia. Selective Catalytic Reduction of NO Using Propane as Reducing Agent.
(Betham Science, 2014-11)
The catalytic behavior of a series of cobalt catalysts supported on zirconia in the selective catalytic reduction(SCR) of NO has been studied using propane as reducing agent. The catalysts were characterized by Raman ...
Characterization of dispersed indium species obtained by thermal treatment of In-NH4-zeolites and their impact on the SCR of NOx
(Elsevier Science, 2011-11)
Indium species dispersed on zeolites by high temperature treatment in air of indium-impregnated NH4-zeolites were characterized and related to the catalytic behavior of the solids in the selective catalytic reduction of ...
The nature of cobalt species in Co and PtCoZSM5 used for the SCR of NOx with CH4
(Academic Press Inc Elsevier Science, 2003-04)
A thorough characterization of CoZSM5 and PtCoZSM5 before and after catalytic use was carried out using a battery of techniques. The bimetallic solid was more selective for N2 production. The TPR profiles showed significant ...
