Palladium catalyst on anodized aluminum monoliths for the partial hydrogenation of vegetable oil
(Elsevier Science SA, 2011-02)
The present work explores the viability of introducing improvements to the conventional process of hydrogenation using structured catalysts. Monolithic catalysts of anodized aluminum were prepared and characterized. They ...
Monolithic reactors for environmental applications: A review on preparation technologies
(Elsevier Science Sa, 2005-05)
The main aspects of preparation technologies for the manufacture of environmental monolithic catalysts have been reviewed on the basis of the patent literature, the authors' own experience in their laboratories, and the ...
Removal of nitrate from drinking water by using PdCu structured catalysts based on cordierite monoliths
(Brazilian Society of Chemical Engineering, 2019-06)
Structured catalysts were prepared, characterized and evaluated in NO3 - removal from drinking water. Different suspensions containing a previously optimized PdCu/5wt% ZrO2-Al2O3 powder catalyst (hereinafter PdCu/5ZAp) ...
Deactivation studies of the SCR of NOx with hydrocarbons on Co-mordenite monolithic catalysts
(Elsevier Science, 2008-06)
The catalytic reduction of NOx with hydrocarbons (butane or methane) on CoMOR washcoated monolithic catalysts was studied in the presence of steam and excess oxygen. The significant changes observed in the catalytic behavior ...
CO preferential oxidation on cordierite monoliths coated with Co/CeO2 catalysts
(Pergamon-Elsevier Science Ltd, 2012-03)
Cordierite monoliths washcoated with Co/CeO2 catalysts prepared from different methods were studied for the CO preferential oxidation reaction. Powder catalysts were also studied for the sake of comparison and in order to ...
Pd/Al2O3-cordierite and Pd/Al2O3-Fecralloy monolithic catalysts for the hydrogenation of sunflower oil
(Elsevier Science, 2009-05)
Monolithic catalysts were prepared using cordierite and Fecralloy as substrates, with Pd/Al2O3 catalyst deposited by a washcoating method. The samples were characterized and studied for the partial hydrogenation of sunflower ...
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 ...
Au/TiO2 supported on ferritic stainless steel monoliths as CO oxidation catalysts
(Elsevier, 2013-01)
Metallic supported structured catalysts were obtained by washcoating AluchromYHf monoliths with an Au/TiO2 catalyst. The powder catalyst was synthesized by DAE (direct anionic exchange) method. Using this catalyst, a stable ...
CO preferential oxidation on cordierite monoliths coated with CuO-CeO2/SBA-15 catalysts. Further insights into the physico-chemical aspects of the catalytic behavior
(Pergamon-Elsevier Science Ltd, 2018-08)
CuO-CeO2/SBA-15 catalysts deposited over cordierite monoliths were prepared to be tested in CO preferential oxidation (COPrOx). The influence of molar ratio between the CuO and CeO2 active phases, their concentration, and ...
