4种天然气基汽车燃料的生命周期3E评价

A EEE and Life Cycle Assessment of Four Natural Gas Based Automotive Fuels

以天然气基汽车代用燃料系统为研究对象,运用生命周期评价方法,评估用天然气生产压缩天然气、甲醇、二甲醚、柴油四种代用燃料系统的生命周期指标,从能源、环境和经济(3E)三方面评价天然气基汽车代用燃料系统;为推广能耗少,对生态环境友好,经济上可接受的能源及能源政策的制定提供依据.

Life Cycle Assessment, Natural Gas based, Substitute Automotive Fuels the objective of this study is to carry out an economic, environmental and energy (EEE)life cycle study to Natural gas based automotive fuels with conventional gasoline in abundant region of China; A set of indexes of four fuels/vechicle systems based on life cycle are assessed in term of impact of EEE, which Natural gas produces compressed natural gas(CNG), methanal, Di-methyl Ether(DME) and Fischer-Tropsch Diesel(FTD); The study included fuel production, vehicle production, vehicle operation, infrastructure, and vehicle end of life as a system for each fuel/vehicle system. A generic gasoline fueled car is used as a baseline. Data have been reviewed and modified based on the best knowledge available to Chongqing local sources .The results indicated that direct use of CNG in a dedicated or bi-fuel vehicle is an economical choice for abundant region in China, which is most energy efficient and more friendly environmental, It's benefit from the results of this study to find a substitute automotive energy and make a energy policy in abundant region.
