中国钢铁生产过程中的CO_2排放现状及减排措施

Current Situation of CO_2 Emission in Iron and Steel Producing and its Controlling Methods

随着我国钢铁产量的逐年提高,我国钢铁工业的碳排放总量呈逐年上升趋势,年碳排量在万t以上,钢铁工业的CO2减排任务面临着巨大的压力。针对我国钢铁产业发展特点,降低能耗、提高能源利用效率、加大废钢重炼以及CO2回收和资源化力度等,是我国钢铁工业实现CO2减排的主要途径。此外,充分利用《京都议定书》中提出的清洁发展机制,也是实现CO_2减排的另一有效措施,这同时也有利于改善我国的能源结构。

CO2 emission is one of the most imperative problems in Chinese iron and steel industry. It can be estimated that much more than 10 thousand tons of CO2 are produced every year in the iron and steel making-process concomitantly, and this number is continuously increasing. Currently, there are several effective methods for CO2 emission control in China, including energy economy, scrap smehing, and recycling of CO2. Furthermore, the practice of CMD can also be utilized for reducing the CO2 emission, as well as improving our energy sources.
