摘要/Abstract

摘要： 一体化技术是燃煤电厂烟气多污染物协同脱除的未来发展趋势。由于工艺简单，固体吸附剂在一体化技术中被广泛研究。综述了近年来备受关注且具有一定应用前景的碳基吸附剂、钙基吸附剂、CuO/γ-Al₂O₃在硫、硝、汞一体化脱除技术中的应用。针对每种吸附技术的脱除原理、研究现状、应用前景和存在的问题进行了分析和总结。指出一体化技术的难点在于协同脱除，以及多种污染物间的相互作用机理的不明确。降低吸附剂成本，提高副产物的利用价值，提高脱硝效率，加强协同脱汞的研究，是未来研究需要关注的重点。最后，对固体吸附剂一体化技术进行了展望，指出该技术对推动中国燃煤电厂多种污染物协同脱除的重要意义。

Abstract: The application of integrated technology is the trend for flue gas pollutants removal in coal-fired power plants. With the simple process as its feature, the solid adsorbents are studied extensively in the integrated pollutants removal technology. Some adsorbents, such as, the carbon-based adsorbents, the calcium-based adsorbents and the CuO/γ-Al₂O₃, which may have good application prospect in the SO₂, NO_x and mercury integrated removal, are reviewed in this paper. The removal mechanisms, research status, application prospect and existing problems for each type of adsorbents are analyzed and summarized. It shows that the mutual influence and interaction mechanism between the different pollutants are still not clear. The future work should focus on the reduction of the adsorbents' cost, the improvement of the by-product utility value, the improvement of the denitrification efficiency and the strengthening of the mercury removal research. Finally, the perspective of the SO₂, NO_x and mercury integrated removal technology by using solid adsorbents is presented to show its significant importance to the pollutants reduction in coal-fired power plants.

Key words: coal-fired power plants, solid adsorbents, integrated removal technology, desulfuration, denitrification, demercuration
