How do greenhouse gas emissions vary with biofertilizer type and soil temperature and moisture in a tropical grassland?
(Science Press, 2020-10-01)
Greenhouse gases are known to play an important role in global warming. In this study, we determined the effects of selected soil and climate variables on nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2) emissions ...
Direct Conversion of Methane to Methanol on Ni-Ceria Surfaces: Metal-Support Interactions and Water-Enabled Catalytic Conversion by Site Blocking
(American Chemical Society, 2018-06)
The transformation of methane into methanol or higher alcohols at moderate temperature and pressure conditions is of great environmental interest and remains a challenge despite many efforts. Extended surfaces of metallic ...
Methane Activation Process: Simultaneous Optimization of Methane Conversion and Aromatic Yields using Zn-ZSM-11 Zeolite
(Bentham Science, 2010-05)
Experiment Design – Response Surface Methodology (RSM) is used to model and to optimize the activation of Methane (C1) using Ethane (C2) as co-reactant into higher hydrocarbons, over Zn-containing zeolite catalyst. The ...
Enteric methane emissions by lactating and dry cows in the high Andes of Peru
(Springer NetherlandsNL, 2022-03-26)
The objective of the study was to determine enteric methane emissions using the sulfur hexafluoride (SF6) technique and comparing with The Intergovernmental Panel on Climate Change (IPCC) methodology in lactating cows (LC) ...
Study of effectiveness factors with non-uniform catalyst distributions for methane steam reforming
(Springer Netherlands, 2020-07-14)
In the present work, three kinetic expressions for methane steam reforming with different methane and water partial pressures dependence were studied. Methane effectiveness factors were simulated for spherical uniform ...

Compreendendo a reação ‘step-wise’ de conversão de metano a metanol usando zeólitas trocadas ionicamente com cobre
(Universidade Federal de São CarlosUFSCarPrograma de Pós-Graduação em Engenharia Química - PPGEQCâmpus São Carlos, 2020-03-06)
Methane (CH4) is a stable molecule abundantly found on our planet with reserves even
greater than crude oil. Due to its high availability and environmental impacts caused by
its emission into the atmosphere, the development ...
Oxidative coupling of methane on cordierite monoliths coated with Sr/La 2 O 3 catalysts. Influence of honeycomb structure and catalyst-cordierite chemical interactions on the catalytic behavior
(Elsevier Science, 2017-11)
When powder Sr/La2O3 catalysts are deposited on the walls of cordierite monoliths, an important increase in both, methane conversion and C2 yield, takes place. In this work, it is shown that this improved catalytic behavior ...
