摘要:
针对煤炭大省山西推进的煤炭产业转型升级、煤炭流动及碳排放变化的情况,依据山西 省煤炭平衡表绘制了2011年和2016年山西省煤流图和碳流图,并进行对比分析。 结果表明:山 西省去库存和增加高附加值煤产品调出效果显著,煤制油、制气技术取得突破,煤炭产业链向精 细化方向发展;煤炭加工转换过程中的固体废弃物和余热得到了资源化利用,供热效率进一步提 升,由2011年的75.6% 上升到2016年的80.2% ;2011—2016 年山西省煤炭相关碳排放总量增 幅较小,发电部门碳排放得到有效控制,但供热部门碳排放上升显著;生活消费碳排放明显下降, 但乡村碳排放为城镇的2倍,是未来碳排放控制的重点区域。 研究结果为山西省未来的煤炭生 产结构调整、煤炭加工技术改进和煤炭相关碳排放控制提供借鉴,对其他面临能源转型的煤炭资 源型省份具有参考意义。
