Catalytic ceramic papers for diesel soot oxidation: A spray method for enhanced performance
(Elsevier Science, 2015-09)
A spraymethod is proposed to improve the catalytic properties of ceramic papers to be used as catalytic lters for removing diesel soot particles. Small particles of Ce and Co oxides, acting as active centers for the ...
Ceramic papers as flexible structures for the development of novel diesel soot combustion catalysts
(Elsevier, 2014-03)
Currently, the most adequate technology for the abatement of particles coming from diesel engines is the one that employs catalytic filters. This work proposes the preparation of catalytic ceramic papers to be employed in ...
Catalytic Abatement of Pollutants from Diesel Exhausts
(Planta Piloto de Ingeniería Química, 2003-12)
K and Co,K supported catalysts were studied to determine the mechanism of the soot combustion. The thermal stability of these catalysts and the resistance to water and sulfur are also addressed. The support plays an important ...
Structured catalyst for the catalytic combustion of soot: Co,Ba,K/ZrO2 supported on Al2O3 foam
(Elsevier Science, 2009-06)
An alumina foam has been coated with a thin layer of ZrO2 by washcoating and impregnated with Co, Ba and K, which are active ingredients for soot combustion and NOx adsorption processes. The ZrO2 coating exhibits an ...
Soot combustion and NOx adsorption on Co,Ba,K/ZrO2
(Elsevier Science, 2008-04)
The aim of this work was to study the Co,Ba,K/ZrO2 catalyst for the removal of the most important pollutants emitted by diesel engines: soot and NOx. The Ba(x)/ZrO2 solids (with "x" varying between 0 and 16 wt.% Ba) and ...
Catalytic paper made from ceramic fibres and natural ulexite. Application to diesel particulate removal
(Elsevier Science Sa, 2017-02)
Ceramic paper discs were made by employing a dual papermaking technique and by partially substituting cellulosic fibres by SiO2-Al2O3ceramic ones. Ulexite (NaCaB5O6(OH)6�5(H2O)), extracted from the natural mineral, was ...
Detonation front structure diagnostics through sooted foilsDiagnóstico da estrutura de frentes de detonação por meio de folhas com fuligem
(2014-07-01)
This work deals with a method for detonation wave front diagnostics through soot foils. The main goal is to develop the method for further detonation research to be developed at the Instituto Tecnológico de Aeronáutica ...
Ultrasound-Assisted Deposition of Co-CeO2 onto Ceramic Microfibers to Conform Catalytic Papers: Their Application in Engine Exhaust Treatment
(American Chemical Society, 2018-12-26)
The combination of the selective catalytic reduction technology with catalytic filters constitutes one of the most efficient ways for diesel engine exhaust treatment. In this paper, the development of catalytic ceramic ...
Single and double-bed stacked wire mesh cartridges for the catalytic treatment of diesel exhausts
(Elsevier, 2019-10)
Stacked stainless steel wire mesh monoliths were developed as supports for Pt/Co,Ce catalysts for diesel exhausttreatment. After the calcination of the metal structures at 900 °C, a Co,Ce layer was deposited over the meshes ...
