Simulation of hydrogen production for mobile fuel cell applications via autothermal reforming of methane [PDF]

open access: yes, 2006
This paper presents a simulation of catalytic autothermal reforming (ATR) of methane (CH4) for hydrogen (H2) production. ATR is essentially an oxidative steam reforming, which combines the exothermic partial oxidation (PO) with the endothermic steam ...

A metagenomic study of methanotrophic microorganisms in Coal Oil Point seep sediments

open access: yesBMC Microbiology, 2011
Background Methane oxidizing prokaryotes in marine sediments are believed to function as a methane filter reducing the oceanic contribution to the global methane emission.

Analytical study of mechanisms for nitric oxide formation during combustion of methane in a jet-stirred combustor [PDF]

open access: yes
The role of chemical kinetics in the formation of nitric oxide during the combustion of methane was examined analytically by means of a detailed chemical mechanism for the oxidation of methane, for the reaction between hydrocarbon fragments, and for the ...

Transport- reaction modeling of marine gas hydrate deposits- global results [PDF]

open access: yes, 2011
We have developed a multi-1D numerical model of gas hydrate formation and dissolution processes in anoxic marine sediments and, by this model, we have estimated the new global gas hydrate inventory (BURWICZ E. B. et al., 2011).

Fractal and Multifractal Analysis of the Rise of Oxygen in Earth's Early Atmosphere

open access: yes, 2015
The rise of oxygen in Earth's atmosphere that occurred 2.4 to 2.2 billion years ago is known as the Earth's Great Oxidation, and its impact on the development of life on Earth has been profound. Thereafter, the increase in Earth's oxygen level persisted,

Study on the effects of trace metal elements on methane oxidation efficiency of microbial community

open access: yesMeikuang Anquan
Metal elements in the environment have a certain impact on key transformation processes in microbial metabolic pathways. In order to study the effect of trace metal elements on the metabolism of microorganisms, the methane-oxidizing bacterial communities

The diversification and potential function of microbiome in sediment-water interface of methane seeps in South China Sea

open access: yesFrontiers in Microbiology
The sediment-water interfaces of cold seeps play important roles in nutrient transportation between seafloor and deep-water column. Microorganisms are the key actors of biogeochemical processes in this interface.

Methane removal efficiency in biochar-methanotroph-clay landfill cover

open access: yesYantu gongcheng xuebao
The landfill is one of the main sources of methane emissions. The landfill cover is at the top of a landfill as an important solution to reduce methane release.

Conjugation effects in ethane oxidation under the conditions of oxidative coupling of methane

open access: yesТонкие химические технологии, 2014
Ethane conversion under the conditions of oxidative coupling of methane (OCM) has been investigated. In an empty reactor above 800°C, ethane oxidation occurs at a higher rate, and its main product is carbon monoxide.
