| 6. | The coal - bed gas is the one kind low pollution energy , and its major composition is methane , a small amount heavy hydrocarbon and some non - hydrocarbon gas bodies ( such as nitrogen gas , the carbon dioxide etc )
煤层气是一种低环境污染能源，其主要成分是甲烷，少量重烃气体和一些非烃气体(如氮气，二氧化碳等) 。 |
| 7. | The coal - bed gas contains many kinds of heavy hydrocarbon gas bodies and the non - hydrocarbon gas , which possesses the characteristic of variable component . if the nature gas engines are fueled with the coal - bed gas directly , they will work abnormally
由于煤层气中含有多种重烃气体和非烃气体，具有组分变化的特点，直接在天然气发动机中燃烧，会使发动机工作不正常。 |
| 8. | Composition of natural gas is different in baimiao and qiaokou , though they are both wet gas . in qiaokou area , the content of methane ch4 % < 80 % , the value of the ratio between methane ch4 and heavy hydrocarbon is about 5 , while in baimiao area , the value of methane ch4 > 88 % , the value of the ratio between methane ch4 and heavy hydrocarbon is more than 10
取得了如下主要认识：白庙与桥口地区天然气虽同属湿气，但成分有一定差异，桥口地区天然气甲烷含量均小于80 ，甲烷重烃为5左右；而白庙地区天然气甲烷含量相近，普遍高于88 ，甲烷重烃10 。 |
