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 ...
Influência do método de preparação e performance catalítica para os catalisadores de Pd-La2O3-Al2O3 aplicados na reforma autotérmica do metano
(Universidade Federal de São CarlosBRUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQ, 2008-05-21)
Pd catalysts supported on Al2O3 and La2O3-Al2O3 (12 wt.% La2O3) were
prepared by wetness impregnation method with aqueous solution of of palladium nitrate
(1 wt.% Pd). The supports were obtained by conventional method ...
Preferential oxidation of CO in presence of H2. Behavior of PtSn/g-Al2O3 catalysts modified by K or Ba
(Planta Piloto de Ingeniería Química, 2007-12)
The behavior of catalysts based on Pt/ -Al2O3 is analyzed in the CO oxidation reaction. Experiments were performed in the temperature range between 50°C and 250°C with a feed H2 rich, and a concentration of 1% CO and 0.6% ...
Influence of TiO2 and AI(2)O(3) on the electrical and microstructural properties of SnO2 ceramics obtained by the Pechini method
(Soc Espanola Ceramica Vidrio, 2008-01-01)
Tin oxide has wakened up great scientific and technological interest for its potential use in varistors production and as gas sensor. In order to improve the microstructural and electrical properties in SnO2 varistor ...
Hydrogen purification for fuel cell using CuO/CeO(2)-Al(2)O(3) catalyst
(ELSEVIER SCIENCE BV, 2011)
CuO/CeO(2), CuO/Al(2)O(3) and CuO/CeO(2)-Al(2)O(3) catalysts, with CuO loading varying from 1 to 5 wt.%, were prepared by the citrate method and applied to the preferential oxidation of carbon monoxide in a reaction medium ...
