摘    要:水泥工业是中国制造业中温室气体CO2的主要排放源,因此,根据水泥生产的基本原理和工艺特点,建立了CO2排放的数学模型并确定排放强度,计算了2001—2010年中国水泥工业CO2的排放量,分析了影响CO2排放量的主要因素及其发展趋势,并提出水泥工业CO2减排对策.结果表明,中国水泥工业CO2排放总量逐年增长,与水泥产量和单位产品原料、燃料消耗定额呈线性关系;在CO2排放总量中,原料煅烧和燃料燃烧阶段的排放量分别占49%和51%;"十一五"期间单位水泥产品CO2排放强度由0.69t.t-1下降到0.65t.t-1.万元GDPCO2排放量呈下降趋势,2008年达到最低值为0.3054t,平均每年万元GDPCO2排放量下降10.69%,说明水泥工业10年间实施节能降耗、资源循环利用、提高经济效益等措施对于减少CO2排放具有明显效果.

关 键 词:水泥工业  温室气体  二氧化碳(CO2)  排放强度  万元GDP

Abstract:The cement industry is a major source of greenhouse gas-carbon dioxide (CO2) emission. According to the principles and characteristics of cement production technique, the mathematical model is established for calculating CO2 emission in cement industry from 2001 to 2010 with the emission factors of production processes and energy consumption. The results indicated that the CO2 emissions increase rapidly every year in China, with a linear relationship between the CO2 emissions and the cement outputs, the comprehensive energy and resource consumption per unit cement product. The raw processing and fuel burning accounts for about 49% and 51% in total CO2 emission of cement industry, respectively. The CO2 emission decreases from 0.69 t·t-1 in the "10th Five-year" plan to 0.65 t·t-1 in the "11th Five-year" plan. The CO2 emissions per ten thousand Yuan GDP decreases to minimum 0.3054 t in 2008, corresponding to 10.69% reduction. The result shows clearly that the saving energy, resource recycling and increase economic efficiency can greatly reduce CO2 emissions.
Keywords:cement industry  greenhouse gas  carbon dioxide(CO2)  emission factor  ten thousand Yuan GDP
