Metal modified silica for catalytic wet air oxidation (CWAO) of glyphosate under atmospheric conditions
(Springer, 2019-10-08)
SBA type nano-structured catalysts were prepared modified with iron and cobalt. The materials were characterized by XRD, N2 adsorption; TEM, ICP–OES, UV–Vis DRS and FTIR. These solids were evaluated in the glyphosate ...
Effect of gas feed flow and gas composition modulation on activated carbon performance in phenol wet air oxidation
(Pergamon-Elsevier Science Ltd, 2007-12)
Modulation of gas feed composition (air/N2 cycling) and gas feed flow (on-off air cycling) was investigated in the catalytic wet air oxidation of phenol over activated carbon (AC). Fifty hours lasting experiments were ...
Catalysis Communications “Catalytic wet air oxidation of phenol aqueous solutions by 1% Ru/CeO2-Al2O3 catalysts prepared by different methods
(Elsevier Science, 2006-07-21)
The wet air oxidation of phenol aqueous solutions (5 g/L) has been studied in a trickle bed reactor (140 º and 7 atm of oxygen pressure). The experiments were performed over several 1%Ru/5%CeO2–Al2O3 samples, prepared by ...
Conventional and wet proofed CuO/Al2O3 catalysts for phenol oxidation: Deactivation studies in a trickle bed reactor
(John Wiley & Sons Ltd, 2007-05)
A large variety of catalytic systems have been studied for the catalytic wet air oxidation of phenolic solutions. Most of them show good activity, but serious stability problems. In this contribution, stability studies ...
Interannual variability of estimated monthly nitrogen deposition to coastal waters due to variations of atmospheric variables model input
(Elsevier Science Inc, 2010-04)
In this work, the influence of the interannual variation of meteorological input data on the nitrogen (N) deposition estimated applying atmospheric dispersion models is discussed. As a case study, the deposition of atmospheric ...
Study of BaCe0.4Zr0.4Y0.2O3-δ/BaCe0.8Pr0.2O3-δ (BCZY/BCP) bilayer membrane for Protonic Conductor Solid Oxide Fuel Cells (PC-SOFC)
(Pergamon-Elsevier Science Ltd, 2020-02)
This paper address the blocking of the electronic conductivity for a BaCe0.8Pr0.2O3-δ (BCP) material due to the addition of a BaCe0.4Zr0.4Y0.2O3-δ (BCZY) thin layer. Barium cerates (BCP and BCZY) show interesting features ...
Metal Organic Framework-Based Sustainable Nanocatalysts for CO Oxidation
(Molecular Diversity Preservation International, 2020-01)
The development of new catalytic nanomaterials following sustainability criteria both in their composition and in their synthesis process is a topic of great current interest. The purpose of this work was to investigate ...
To burn or not to burn : the question of straw burning and nitrogen fertilization effect on nitrous oxide emissions in sugarcane
(2017)
Nitrous oxide (N2O) is the main greenhouse gas emitted from farming systems and is associated with nitrogen (N) fertilizer application as well as decomposition of organic matter present in the environment. The objective ...
