摘　　要：煤炭基于发热量的碳含量数据,是计算煤炭的二氧化碳排放因子的基础。本研究对全国范围内采集的煤炭样品进行工业分析、元素分析及发热量分析,统计分析得出我国基于发热量的煤炭碳含量。对所得结果按地区分煤种分别阐述,并与国外煤炭碳含量数据进行了对比。结果表明,我国褐煤、次烟煤、烟煤、无烟煤的碳含量平均值分别为27.21±0.35kg/GJ、26.57±0.14kg/GJ、25.50±0.03kg/GJ、26.77±0.13kg/GJ。我国无烟煤的碳含量与IPCC缺省值相当,烟煤、褐煤的碳含量比IPCC缺省碳含量分别低1.16%和1.41%,次烟煤碳含量比IPCC缺省碳含量高1.41%。The data of coals on carbon content per unit energy are needed when calculating the CO2 emission factors of coals. In this study, 305 coal samples were collected from all over China, and analyzed by means of proximate analysis, gross calorific value analysis and ultimate analysis. The average carbon content per unit energy of Chinese coals on an energy basis was calcu- lated according to these results. The average carbon content per unit energy of anthracite is close to the IPCC default value, which is 26.77±0.13kg/GJ. Those values of bitumite and lignite, which are 25.50-±0.03kg/GJ and 27.21±0.35kg/GJ, re- spectively, are 1.16% and 1.41% lower than the IPCC default values, respectively. The carbon content per unit energy of sub- bituminous coal is 26.57±0.14kg/GJ, which is 1.41% higher than the IPCC default value.
