The purpose of our design project is to produce a high purity hydrogen product that emits a low concentration of carbon dioxide emissions. The objective will be to replace the current industrial standard of steam reforming which doesn't produce a marketable byproduct as well as producing high amount of carbon dioxide emissions. Throughout the semester,

Dissolved Methane Sensor for Methane Leakage Monitoring in Methane Hydrate Production
OCEANS 2006, 2006This paper describes the development of a dissolved methane sensor that will be used for the methane leakage monitoring in the methane hydrate production in Japan in the future. As for the requirements for the sensor, continuous, long-time use in a great water depth, real-time measurement, and outstanding response to the change of dissolved methane ...

Methane combustion in hydrate systems: Water-methane and water-methane-isopropanol
Journal of Engineering Thermophysics, 2013Kinetics of dissociation of synthetic and natural methane gas hydrates, and also double isopropanol-methane hydrate is investigated. Thermal fields of the sample surfaces are measured by means of thermal imaging in combustion of released methane with clathrate dissociation.

Methane Monooxygenase: Functionalizing Methane at Iron and Copper
2014Methane monooxygenases (MMOs) catalyze the conversion of methane to methanol as the first committed step in the assimilation of this hydrocarbon into biomass and energy by methanotrophs, thus playing a significant role in the biogeochemistry of this potent greenhouse gas.

The recent downturn in natural gas prices worldwide has opened up an avenue for alternative chemistry methods to create hydrocarbon products such as aromatics. One such process proposed by my senior design group involves using a catalyst to convert methane directly to benzene and toluene, with the formation of hydrogen and naphthalene byproducts.

Nature, 2014
Methane is a potent greenhouse gas with many times the global warming potential of carbon dioxide, so understanding how its emissions might change with increasing temperature is important for climate predictions. These authors conduct a meta-analysis of the temperature dependence of methane emissions from studies of laboratory cultures, environmental ...

Methane is a suffocating gas, and "methane deaths" are largely the result of suffocation by gas-air displacement after accidental or deliberate exposure. Neither methane gas nor other suffocating gases are a common means of homicide, with the potential exception of the use of gas in chemical weapons or gas chambers.

The homogeneous partial oxidation of methane involves the primary reactions of methane oxidation as well as the secondary reactions with the reaction products formaldehyde, methanol, and carbon monoxide. The complex free-radical set of reactions are modeled using a pseudo-first-order reaction parallel-series network of the three reactions: methane to ...

methane production and methane consumption a review of processes underlying wetland methane fluxes [PDF]
Biogeochemistry, 1998 Potential rates of both methane production and methane consumption vary over three orders of magnitude and their distribution is skew. These rates are weakly correlated with ecosystem type, incubation temperature, in situ aeration, latitude, depth and distance to oxic/anoxic interface.
