摘要
本文通过分析有色金属工业的碳排放现状,指出碳排放主要发生在冶炼环节,尤其是铝冶炼环节,并提出了有色金属工业实现碳中和的三个主要途径:使用清洁能源、提高能源利用率和发展CCUS技术。其中,氢能是有色金属工业清洁能源的首选;提高能源利用率可通过开发新工艺和淘汰落后工艺、提升关键设备设计制造水平、发展热能梯级利用技术来实现。有色金属工业应加紧布局,确保各阶段碳中和目标如期实现。
This paper analyzed the current situation of carbon emission in nonferrous metal industry,pointed out that carbon emission mainly occurred in smelting process,especially in aluminum smelting process,and put forward three main ways to realize carbon neutralization:using clean energy,improving energy utilization rate and developing CCUS technology.Among them,hydrogen energy was the preferred clean energy for nonferrous metal industry;The improvement of energy utilization can be achieved by developing new processes and eliminating backward processes,improving the design and manufacturing level of key equipment,and developing thermal energy cascade utilization technology.The nonferrous metal industry should intensify its layout to ensure that carbon neutrality targets at all stages were achieved on schedule.
