煤利用中汞控制技术的分析研究

Research and Analysis for Control of Mercury from the Use of Coal

煤利用中汞污染已经成为威胁全球的环境污染问题,本文概述了目前在研的多种煤利用中汞控制技术的研究现状,对目前已有的脱汞技术进行了概述,重点介绍活性炭、飞灰、钙基吸附剂及矿物类吸附剂等。在对现有脱汞技术总结和分析的基础上,对该领域今后的主要发展方向进行展望。

Mercury pollution from the use of coal has caused serious environmental problem in the whole world. The paper reviewed the control technology of mercury during the conversion of coal, the current technologies for Hg capture were summarized, and the active-carbon, fly ash, calcium-based and mineral sorbents were emphatically introduced. On the base of the summary and analysis of the control technology of mercury, some advices were proposed for the further research and development in this field.
