CO2 emissions are estimated based on their sources. The specific estimation method is as follows:①CO2 produced from carbonate decomposition. During the cement production process, the decomposition of limestone to produce cement clinker requires CaO, which also generates CO2. The chemical reaction is as follows: CaCO3→CaO+CO2↑. The chemical equation for the decomposition of CaCO3 shows that for every 1 part of CaO produced, 0.7857 parts of CO2 are also generated. Based on the average content of CaO in the main mineral components of ordinary Portland cement in China, which ranges from 62% to 67%, assuming 65%, the CO2 produced from the decomposition of CaCO3 for every ton of cement clinker produced is: 1 ton × 0.7857 × 65% = 0.5071 ton. In addition, cement raw materials usually contain a small amount of magnesium carbonate, which also decomposes and produces CO2 during calcination. The chemical reaction is as follows: MgCO3→MgO+CO2↑. The chemical equation for the decomposition of MgCO3 shows that for every 1 part of MgO produced, 1.1 parts of CO2 are also generated. Based on the average content of MgO in the main mineral components of ordinary Portland cement in China, which ranges from 1% to 3%, assuming 1.5%, the CO2 produced from the decomposition of magnesium carbonate for every ton of cement clinker produced is: 1 ton × 1.1 × 1.5% = 0.0165 ton. In summary, the total amount of CO2 produced from carbonate decomposition during cement clinker production is: 0.5071 ton + 0.0165 ton = 0.5236 ton.②CO2 emitted from cement kiln fuel combustion. The formation of cement clinker requires high-temperature calcination, during which CO2 is generated from fuel combustion to provide high temperature. According to research results from the IPCC, the carbon emission factor of raw coal in China is 2.7715 kg CO2/kg of raw coal.CO2。CO2排放按其来源进行估算。具体估算方法如下：①碳酸分解产生的CO2。水泥生产过程中石灰石的分解生成水泥熟料必须的Cao同时会生成CO2，其化学反应式为： CaCO3→Cao+CO2 ↑。CaCO3分解的化学反应式表明：每生成1份的Cao，同时会生成0.7857份的 CO2，根据国内的平均水平，我国普通硅酸盐水泥的主要矿物化学成分中CaO含量的大致波动范围为：62-67％，如果按65%计算，每生产1吨水泥熟料，由CaCO3分解产生CO2为：1t×0.7857×65％=0.5071t。 另外，水泥生料中通常含有少量的碳酸镁，碳酸镁在煅烧过程中分解也会产 生CO2，其化学反应式为：MgCO3→Mgo+CO2↑。MgCO3分解的化学反应式表明：每生成1份的 Mgo，同时会生成1.1份的CO2，根据国内的平均水平，我国普通硅酸盐水泥的主要矿物化学成分中MgO含量的大致波动范围为：1-3％，如果按1.5%计算，每生产1t水泥熟料，由碳酸镁分解产生的CO2为：1t×1.1×1.5％＝0.0165t。 综合计算，在水泥熟料生产过程中，由碳酸盐分解产生的CO2总量为：0.5107t + 0.0165t=0.5272t。②水泥窑燃料燃烧排放的CO2。水泥熟料的形成需要高温煅烧，煅烧过程中燃料燃烧提供高温的过程中会生成CO2，根据IPCC的研究成果，我国原煤的碳排放系数为2.7715kgCO2/kg原煤。carbon monoxide (fossil)Output0.1080.108COCOmethane (fossil)Output1.221.22CH4CH4cement, ordinary portland cementOutput1000.01000.0Ordinary Portland Cement普通硅酸盐水泥
