天然气是低碳烃的混合物,主要成分为甲烷,由于形成的地质条件不同,一般含有乙烷、丙烷和丁烷等烃类化合物,还有可能包含二氧化碳、氮气、氢气、硫化物等非烃类气体。天然气经分离和脱硫后,基本不含其他有害杂质,与石油和煤炭相比,只产生极少的二氧化硫,微量的一氧化二氮,二氧化碳排放量少,不产生悬浮粒子,用后也无废渣。是一种高效和清洁的燃料。 Natural gas is a mixture of low-carbon hydrocarbons, the main component of methane, due to the formation of different geological conditions, generally containing hydrocarbons such as ethane, propane and butane, may also contain carbon dioxide, nitrogen, hydrogen, sulfide and other non-hydrocarbons gas. After separation and desulfurization of natural gas, it is basically free of other harmful impurities. Compared with petroleum and coal, natural gas produces only very small amount of sulfur dioxide and trace nitrous oxide. It has less carbon dioxide emissions, no suspended particles and no residue after use . Is a highly efficient and clean fuel.
