Raman characterization of single-walled nanotubes of various diameters obtained by catalytic disproportionation of CO
(American Scientific Publishers, 2003-02-01)
Single-walled carbon nanotubes prepared by disproportionation of CO over Co-Mo/SiO 2 catalysts have been characterized by Raman spectroscopy, using several excitation energies. By varying the reaction temperature, different ...
Catalytic coating synthesized onto cordierite monolith walls. Its application to diesel soot combustion
(Elsevier Science, 2012-12)
Co,Ba,K/ZrO2 coating onto a cordierite monolith was produced using a sequential process. The first step involved the formation of a ZrO2 layer using a colloidal suspension and the second, the incorporation of active metals. ...
Ethanol steam reforming over cobalt talc in a plate microreactor
(Elsevier Science Sa, 2011-12)
Stainless steel plates were coated with cobalt talc (Co 3[Si 2O 5] 2(OH) 2) and used in a catalytic plate microreactor for producing hydrogen from ethanol steam reforming at low temperature. Cobalt talc was deposited ...
Heterogeneous Two-Region Model for Low-Aspect-Ratio Fixed-Bed Catalytic Reactors. Analysis of Fluid-Convective Contributions
(American Chemical Society, 2014-02-21)
ABSTRACT: A two-region, two-dimensional (2R2D) model aimed at improving the heat transfer description of multitubular catalytic reactors is introduced here. The effects concentrated in the wall thermal resistance (1/hw) ...
Catalytic walls and micro-devices for generating hydrogen by low temperature steam reforming of ethanol
(Elsevier Science, 2009-05-21)
Ethanol steam reforming (S/C = 3) was effectively performed at low temperature over catalytic wall reactors comprising a wide range of channel dimensions, ranging from conventional monoliths (channel width of 0.9 mm) to ...
Immobilization of ruthenium phthalocyanine on silica-coated multi-wall partially oriented carbon nanotubes: Electrochemical detection of fenitrothion pesticide
(Elsevier B.V., 2016-04-01)
This paper reports on the determination of the pesticide fenitrothion using a glassy carbon electrode modified with silica-coated, multi-walled, partially oriented carbon nanotubes, SiO2/MWCNTs, containing ruthenium ...
Development of sepiolite/SiC porous catalytic filters for diesel soot abatement
(Elsevier Science, 2016-08)
Honeycomb monoliths made up of 70 wt.% sepiolite and 30 wt.% SiC were prepared and macropores were generated in the honeycomb structure by introducing a temporary additive with the aim of obtaining an adequate porosity to ...
