Natural source Super Low Frequency(SLF) electromagnetic prospecting methods have become an increasingly promising way in the resource detection. The capacity estimation of the reservoirs is of great i...
Since the beginning of the industrial revolution, the atmospheric concentration of carbon dioxide (CO2) has increased by nearly 30%, and the Methane (CH4) concentration has more than doubled. CH4 is t...
As clean substitute energy source, coal bed methane is widely attractive worldwide. Remote sensing plays very important role in coal exploration in past experiences, it is also potential in coal bed m...
Based on analysis of the significance of the coal bed methane exploration and development and the deficiency of the conventional coal bed methane exploration methods, the paper proposes a new technolo...
 Though they occupy a small fraction of the Earth's surface, freshwater wetlands are the largest natural source of methane going into the atmosphere. New research from the University of Georgia i...
Ignitability and the ignition delay time of a combustible mixture in a long combustion chamber, ignited by a hot combustion torch jet generated in a pre-chamber was investigated experimentally in rela...
Rice cultivation has been recognized as one of the major anthropogenic source for methane (CH4) emissions which is a microbial mediated anaerobic activity, mainly favoured by the flooded conditions in...
CORVALLIS, Ore. – Since the first undersea methane seep was discovered 30 years ago, scientists have meticulously analyzed and measured how microbes in the seafloor sediments consume the greenhouse ga...
Athens, Ga. - The 2010 Deepwater Horizon blowout discharged roughly five million barrels of oil and up to 500,000 metric tonnes of natural gas into Gulf of Mexico offshore waters over a period of 84 d...
pThe widely reported paradox of methane oversaturation in oxygenated water challenges the prevailing paradigm that microbial methanogenesis only occurs under anoxic conditions. Using a combination of...
HOUSTON – (Jan. 22, 2014) – Rice University scientists have created a highly sensitive portable sensor to test the air for the most damaging greenhouse gases.
Ni/γ-Al2O3, Ni/Y-zeolite, and Ni/H-ZSM-5 catalysts were prepared using the incipient wetness impregnation method. Their catalytic performance in dry reforming of methane was studied. The fresh and use...
Because it is a greenhouse gas, the detection of methane concentrations is a global issue. Additionally, the presence of methane is indicative of potential valuable petroleum and natural gas deposits....
A series of ternary perovskite type oxides LaNi1-xCuxO3 (x = 0.2, 0.4, 0.6, 0.8, and 1.0) were synthesized via the sol-gel method in propionic acid. Partial substitution of Ni by Cu showed higher acti...
Concentrations of non-methane hydrocarbons (NMHCs) were measured to investigate their temporal variations and major sources, and to explore the ozone formation potentials (OFP) of each NMHCs for the ...
