| Abstract: |
| Coalbed methane (CBM) composition analysis in China is adopting the natural gas sampling and analysis standards at present. In this paper, the applicability of these standards for CBM was studied by theoretical evaluation and experimental verification. The results show that most of the existing methods are suitable for CBM, some methods still need to be improved for CBM quality analysis. Based on these studies, the proposals for improvement of CBM analysis methods and standardization are put forward. |
