摘要
在V_2O_5-WO_3/TiO_2催化剂体系中,载体TiO_2约占80%以上的比例,其相关性能对催化剂制造具有重要影响作用,特别是其粘度的影响。现针对生产SCR用脱硝载体TiO_2的工艺,分析了载体TiO_2的基本性能如比表面积、硫含量、p H值、粒径和颗粒物含量对其粘度的影响,实验结果表明,上述因素对其粘度的影响显著,而这些影响因素在工业化工艺中是可控的,由此,可获得SCR催化剂专用TiO_2粉体。
The proportion of carrier TiO_2 is accounted for more than 80% in V_2O_5-WO_3/TiO_2 catalyst system,and plays an important role on the catalyst manufacturing,especially the influence of the viscosity. According to the production process of SCR denitration,the properties of TiO_2 was analyzed on the viscosity,such as specific surface area,sulfur content,the p H value,particle size and particla content. As the results,these factors were significant on the influence of the viscosity. But these factors can be controlled in the industrialization. Using this method,the special quality TiO_2 powders were obtained as carrier for SCR de-NO_xcatalyst.
