摘要：针对燃煤电厂SO_(2)排放法规日趋严格,而传统固硫剂高温固硫性能差的问题,设计了Ce-Mn/Al_(2)O_(3)复合催化剂降低燃煤中硫排放的综合实验。以纳米Al2O3为载体,采用共沉淀法制备了Ce-Mn负载型燃煤催化剂,在管式炉中进行高温固硫性能评价实验,采用热重法分析煤粉的燃烧性能,得到反应动力学参数。采用FESEM-EDS、TEM、XRD、XPS对催化剂进行表征。实验结果表明,Ce-Mn催化剂可以显著提高燃煤固硫效果,改善煤粉燃烧性能。该实验不仅能加深学生对脱硫工艺原理和应用的理解,掌握仪器使用、软件绘图和催化剂表征手段,还能增强学生对燃料清洁利用的认识,培养科研思维和创新能力。
In response to the increasingly strict SO_(2)emission regulations in coal-fired power plants and the poor high-temperature sulfur fixation performance of traditional sulfur fixing agents,a comprehensive experiment was designed to reduce sulfur emissions in coal using Ce-Mn/Al_(2)O_(3)composite catalysts.Ce-Mn-loaded coal-fired catalysts were prepared using the co-precipitation method using nano Al_(2)O_(3)as the carrier.High-temperature sulfur fixation performance evaluation experiments were conducted in a tube furnace,and the combustion performance of coal powder was analyzed using the thermogravimetric method to obtain reaction kinetics parameters.The catalyst was characterized using FESEM-EDS,JEM,XRD,and XPS.The experimental results indicate that the Ce-Mn catalyst can significantly improve the sulfur fixation effect of coal combustion and improve the combustion performance of coal powder.This experiment can not only deepen students’understanding of the principles and applications of desulfurization technology,master instrument usage,software drawing,and catalyst characterization,but also enhance students’understanding of clean fuel utilization,and cultivate scientific research thinking and innovation ability.
