中文摘要：

以石化工业副产物高硫石油焦制备的活性炭为脱汞吸附剂，对其进行NH。Br溶液浸渍改性成为载溴富硫活性炭。采用N2吸附／脱附、扫描电子显微镜／）（射线能谱仪（scanning electron microscopy/X-ray energy dispersive spectroscope,SEM/EDS）等方法对吸附剂进行孔隙结构和微观形貌表征。分别在固定床反应器和管道喷射实验装置上进行汞吸附脱除实验研究。与煤制活性炭相比，高硫石油焦活性炭具有更高的汞吸附能力，经过质量分数为1％的NH4Br溶液改性后，石油焦活性炭固定床120min内汞脱除率接近100％；在120℃、2S停留时间、碳汞比约为90000条件下，喷射脱汞效率亦超过90％。实验结果表明，溴化铵改性高硫石油焦活性炭可作为燃煤电厂烟气喷射脱汞的高效吸附剂。

英文摘要：

As a petrochemical industry by-product, petroleum coke With high sulfur content was made into activated carbon, and then treated by NH4Br solution for modification with Br uploading on its surface. The prepared petroleum cokes were characterized by means of nitrogen （N2） adsorption/desorption, and scanning electron microscopy/X-ray energy dispersive spectroscope （SEM-EDS）. Experimental studies on Hg removal were investigated in both a fixed bed and an entrained flow reactor system. Petroleum coke activated carbon modified by NH4Br performs better mercury adsorption capacity than commonly used activated carbon from coal. It is noted that 1% additive of NH4Br into the petroleum coke activated carbon nearly remove all the mercury in a fixed bed within 120rain, and the mercury removal efficiency of entrained flow reactor system under condition of 120 ℃, 2 second residence time and about 90 000 C/Hg ratio is above 90%. The results solidly support that the modified high sulfur petroleum coke can be used as high effective mercury removal adsorbent in a flue gas injection of demercuration system for coal fired power plant.
