A.Because it's too difficult to find the place where the fire ice lies and how to drill it.B.Because it's not easy for fire ice to go into the air and be good for the environment.C.Because it’s quite impossible for fire ice to take the place of other sources of energy.D....
More recently, the role played by methane as a potent "greenhouse" gas has aroused considerable attention from environmentalists and clima tologists alike. This role for C compounds has, of course, been quite 1 incidental to the myriad of microorganisms on this planet that have adapted ...
Permafrost and glaciers in the high Arctic form an impermeable ‘cryospheric cap’ that traps a large reservoir of subsurface methane, preventing it from reaching the atmosphere. Cryospheric vulnerability to climate warming is making releases of this methane possible. On Svalbard, where air temperatures...
The firm — which imports some 12.6 million tonnes of liquefied natural gas a year to 8.6 million retail and wholesale customers, and for power generation — wants to find an alternative source of methane that has far less impact on the environment, says Yakabe. ...

Dry methane reforming (DMR) or CO2 reforming is the third common form of reforming process. In this process, syngas with a H2/CO ratio of 1:1 is produced according to the following reaction: (8)CH4+CO2⇔2CO+2H2,ΔH=247kJ/mol This reaction was originally proposed by Fischer and Trops...
Defining the character of the methanogenic types with carbon and hydrogen isotopes not only provides information about the environment of formation, it is also most useful in distinguishing biogenic from thermogenic methane gases. 展开 DOI: 10.1016/0016-7037(86)90346-7 被引量: 2163 ...
Methane is the main component in natural gas, which fuels industrial plants, powers homes and runs air conditioners, among other applications. Why do methane emissions pose a risk to the environment? Methane is about 80 times more powerful at warming the atmosphere than carbon dioxide over a 20...
