Different bulk transition-metal oxides (NiO, CuO, Mn2O3, Cr2O3, and Co3O4) were prepared, by precipitation from nitrate precursors, and tested for the combustion of methaneair lean mixtures (10005000 ppmv of CH4). Catalyst performances were compared in terms of both intrinsic activity and ...
It is a chemical reaction that involves the oxidation of the fuel, which is usually a hydrocarbon, with oxygen to produce carbon dioxide and water vapor. The reaction is exothermic, meaning that it releases heat energy as a product. The chemical equation for the complete combustion of methane,...
Methane combustion Instability Von Karman vortex street Obstacle of cylindrical shape Mathematical model 1. Introduction Flame instability in practical combustion systems has been a topic of great interest due to numerous difficulties in understanding of the coupling of fluid dynamics, chemical kinetics and...
Our results show that anthropogenic enrichment is not required to elevate this ratio, and instead indicate that climate-mediated pressure (i.e., seasonal drought events) at high latitudes may routinely alter the metabolic character of headwater environments, favoring methane production....

Aerosol particles from the combustion of fossil fuels or other sources are another source of HM pollution that can easily contaminate our agricultural areas by spreading in the atmosphere. Moreover, the increased use of phosphate fertilizers [19] also affects the contamination levels of soils and, ...
