燃气作为汽车替代燃料的应用现状及存在的问题

Application Status and Existing Problems of Gas used as Vehicles Alternative Fuel

随着我国汽车保有量的迅速增加和天然气在一次能源中重要性的提高,以燃气作为新型汽车替代燃料具有很好的可行性。这类汽车替代燃料主要包括压缩天然气(CNG)、液化石油气(LPG)、液化天然气(LNG)、合成甲醇、二甲醚(DME)以及天然气合成油(GTL)等。文章对它们的应用现状和存在的问题进行了分析和讨论。

With the rapid increase of the car ownership in our countryand the enhancing importance of natural gas in primary energy, the gas as the new type car alternative fuel has a good feasibility. These vehicles alternative fuels include compressed natural gas （CNG）, liquefied petroleum gas （LPG）, liquefied natural gas （LNG）, methanol synthesis, dimethyl ether （DME）, and natural gas liquids （GTL） and so on. Their application status and existing problems are analyzed and discussed.
