4种天然气基汽车燃料的生命周期3E评价

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.
