煤层气汽车燃料的生命周期温室气体排放分析

Analysis on Greenhouse Gas Emission of Lifecycle for Automobile Fuel of Coal Bed Gas

煤层气是一种清洁、高效、低碳的替代能源,在我国交通运输领域有非常广阔的应用前景。文章基于对各类运输企业调研获得的实际运营能耗数据,对煤层气车辆和燃油车辆在燃料燃烧阶段的CO_2、CH_4、N_2O三种温室气体排放情况进行了实际测算,同时从生命周期的视角对煤层气用作汽车燃料和油品燃料的上游温室气体排放进行了考查,对煤层气汽车相比燃油汽车在温室气体减排方面的效益作出了客观评价。

The coal bed is a substituting energy in the ifelds of cleanness, high efifciency and low carbon, it has a very wider application prospect in the transportation area. Based on the actual operation energy consumption data obtained in the investigation and research of al kinds of the transportation enterprises, the paper carries out the actual measures of three kinds of greenhouse gas emission status of CO2、CH4、N2O in the fuel incineration phase on coal bed gas vehicle and fuel vehicle. At the same time, from the angle of view of lifecycle, the coal bed gas which is used as greenhouse gas emissions at top stream of automobile fuel and oil fuel, is examined and the objective assessment in the beneifts of the greenhouse gas emission is made in comparison between automobile of coal bed gas vehicle and fuel vehicle.
