CH4

Methane (CH4) is the main constituent of natural gas, and is the result of natural decomposition processes.

The results indicate that CNTs grown using CH4 and H2 as reaction gases are bent and hollow, with a large average diameter and a low.

While oil poses undeniable ecological risks, methane (CH4) could prove daunting as well.

Because CH4 content value is quite different in regional strata in Jiucaiping area, the unified index is adopted to appraise the whole area.

The CH4 emission before and after cutting in forest wetlands had minor correlation with the water level.

The element's sensitive mechanism to CH4 gas is also discussed in the end of this paper.

Development of the study on methane activation mechanism in recent years have been reviewed in this article.

Natural gas is a combustible gas which major component is CH4, and release heat when burning.

CH4 uptake flux also had obvious diurnal variation, higher in the daytime and lower in night.

Their catalytic activities in partial oxidation of CH4 were studied.

CH4 production and its effect on the forest carbon cycling.

The key of controlling CH4 emission lies in regulating irrigation water.

From the calculations, we conclude that the C-addition path is the most favorable and the major products are HCN, CH4 and C2H6.

The emission of CH4 and N2O increased basically with acidification cumulation degree.

methane(ch 4 ) has both natural and anthropogenic sources.

the CH4 mixing ratio decreases from low latitude to high latitude.

It is estimated that some 50 billion tons of CH4 could be trapped in the Siberian Lake permafrost.

CH4 content declined with the increase of temperature, residence time and heating rate.

and CH4, which is a new energy generated by methanogens from CO2, is the beneficial complement of the energy.

But a large proportion of global greenhouse gas emissions are actually other gases, such as N2O (nitrous oxide) and CH4 (methane).

CH4, with a net lifetime of 10 years, can also degrade the ozone layer.

The relative difference of CH4 production and emission explained very well the CH4 oxidation potential of different treatments.

CH4 8RF or another site by mutual prior agreement.

The average emission rate under ZTSR was lower 24. 3% and 27% than CTSR and RTSR, respectively.

With the increase of the pressure, the flux both of CO2 and CH4 increase but the separation factor declines;
