100037 摘要: 我国褐煤资源较为丰富, 主要分布于内蒙古东部、云南省和黑龙江省.褐煤主要的传统利用方式 是直接燃烧发电, 但其存在能效低、污染重等问题.除发电外, 褐煤新型利用方式逐渐成熟, 制取天然气以 及提质后发电就是其中的代表.本文基于全生命周期评价法, 计算了褐煤制取天然气与褐煤提质后发电在 终端利用能效相同的情况下,产生1GJ 有效能量的温室气体排放量,分别为158.173/e kg/GJ、 480.68/e kg/GJ(e 为能源终端使用能效).显然, 从温室气体排放角度, 褐煤制取天然气优于提质褐煤发电技 术. 关键词: 提质褐煤发电;

100037 Abstract: China has relatively abundant lignite, which is mainly distributed in eastern Inner Mongolia, Yunnan Province and Heilongjiang Province. Traditionally, the thermal power generation is the predominant way to use lignite;

nevertheless, it is also the way with low energy utilization rate and high pollution. In addition to power generation, new technologies dealing with lignite have matured. Lignite-based synthetic natural gas production and power generation with lignite upgrading technology are of representativeness. Based on Life Cycle Assessment, this paper compared the Greenhouse Gas (GHG) emissions of 1GJ output of effective energy between lignite-based Synthetic Natural Gas (SNG) production and power generation with lignite upgrading technology under the condition of the same energy efficiency of end use. They are respectively 158.173/e kg/GJ, 480.68/e kg/GJ (e as the energy efficiency of end use). Obviously, the life cycle GHG emission of lignite-based SNG production is significantly less than that of the upgraded lignite-power generation. Key words: upgraded lignite-power generation;

greenhouse gas emissions 褐煤是煤化程度最低的矿产煤, 具有水分大 (20%~60%)、发热量低(10~20 MJ/kg), 挥发分含量 高、运输半径小等特征.直接燃烧将产生大量的二 氧化碳.截至
