摘要
研究文献表明煤燃烧或气化过程中,微量元素的迁移特性主要取决于元素的挥发性,挥发性越高的元素则越易进入气相,反之则越易留在灰渣中。以新疆某煤制气项目为例,探讨煤化工环评中如何计算微量有毒有害元素物料平衡。
Studies show that in coal combustion and gasification processes, migration regular of trace elements in coal is mainly determined on volatilization of elements. If the element＇s volatile is higher, it will be easier to migrate to gas phase. Whereas it will be more easy to stay in the ash. In the study, a Coal gasification project in Xinjiang has been cited to discuss the material balance of harmful trace elements in coal chemical industry
