| 1 | VMoTi/玻纤复合催化滤布制备及其除尘协同脱硝性能研究显示文摘采用浸渍法制备出具有脱硝除尘功能的VMoTi/玻纤复合催化滤布,研究了VMoTi/玻纤复合催化滤布的脱硝除尘性能。考察了负载量、黏结剂、反应温度、过滤风速、SO_(2)和H_(2)O对脱硝除尘性能的影响,通过SEM、XRD及EDS表征手段进行分析,结果表明:当负载量为130 g/m^(2),过滤风速为0.5 m/min,在200-250℃下,脱硝效率为60%-85%。且在定压喷吹老化500次后,脱硝效率无明显下降,表现出良好的脱硝性能稳定性。通入SO_(2)和H_(2)O后,脱硝效率维持在75%以上,具有良好的抗水硫性能。VMoTi/玻纤复合催化滤布除尘效率在99.99%以上,满足实际工业烟尘治理应用要求。 | 单良 尹荣强 王慧 费传军 周清清 徐杰 王志强 徐涛 陈建军 李俊华 | 2021 | 化工学报2021，72，9： | 6 |
| 2 | 用于空气净化的双疏膜制备及应用进展显示文摘工业烟气中经常含有大量油性气溶胶,而传统过滤材料基本都是亲油性的,导致吸附污染严重。双疏型膜材料在面向高湿、含油性气溶胶的复杂烟气体系时,具有分离效率高、抗污染性强和易清洁等优点。本文系统总结了用于空气净化过程的双疏膜材料制备方法,通过对应用过程油性气溶胶与膜表面之间的微观作用分析,阐释了影响膜污染形成与控制的表界面作用机理。最后,对双疏膜材料在空气净化领域的发展前景做了分析和研讨。 | 朱肖 冯厦厦 仲兆祥 邢卫红 | 2021 | 化工学报2021，72，1： | 4 |
| 3 | NO removal performance of CO in carbonation stage of calcium looping for CO_(2) capture显示文摘Calcium looping realizes CO_(2)capture via the cyclic calcination/carbonation of CaO.The combustion of fuel supplies energy for the calciner.It is unavoidable that some unburned char in the calciner flows into the carbonator,generating CO due to the hypoxic atmosphere in the carbonator.CO can reduce NO in the flue gases from coal-fired power plants.In this work,NO removal performance of CO in the carbonation stage of calcium looping for CO_(2)capture was investigated in a bubbling fluidized bed reactor.The effects of carbonation temperature,CO concentration,CO_(2)capture,type of CaO,number of CO_(2)capture cycles and presence of char on NO removal by CO in carbonation stage of calcium looping were discussed.CaO possesses an efficient catalytic effect on NO removal by CO.High temperature and high CO concentration lead to high NO removal efficiency of CO in the presence of CaO.Taking account of better NO removal and CO_(2)capture,the optimal carbonation temperature is 650℃.The carbonation of CaO reduces the catalytic activity of CaO for NO removal by CO due to the formation of CaCO_(3).Besides,the catalytic performance of CaO on NO removal by CO gradually decreases with the number of CO_(2)capture cycles.This is because the sintering of CaO leads to the fusion of CaO grains and blockage of pores in CaO,hindering the diffusion of NO and CO.The high CaO content and porous structure of calcium-based sorbents are beneficial for NO removal by CO.The presence of char promotes NO removal by CO in the carbonator.CO_(2)/NO removal efficiencies can reach above 90%.The efficient simultaneous NO and CO_(2)removal by CO and CaO in the carbonation step of the calcium looping seems promising. | Wan Zhang Yingjie Li Yuqi Qian Boyu Li Jianli Zhao Zeyan Wang | 2021 | Chinese Journal of Chemical Engineering2021，34，9： | 1 |
