| 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1 GJ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。

| 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. |
