一种锰钨钛硅脱硝催化剂及其制备与应用
摘要：
本发明公开了一种以锰钨钛硅基脱硝催化剂及其制备与应用，所述的催化剂MnWOx/TiO2-SiO2以溶胶凝胶法制备TiO2-SiO2复合氧化物载体，以液相沉积法负载MnWOx为活性组分，所述的活性组分MnWOx的质量占催化剂总质量的5-30％，所述的载体TiO2-SiO2复合氧化物的质量占催化剂总质量的70-95％，所述的载体中SiO2的质量占载体总质量的1-50％。所述的催化剂在170-350℃温度窗口内有90％以上的NO转化率以及90％以上的N2选择性。Mn2WOx/TiO2-SiO2催化剂在含硫烟气下运行，具有良好的抗硫性能，可应用于较低温条件下的选择性催化还原脱硝。
摘要（英）：

The invention discloses a MnWOx/TiO2-SiO2 denitration catalyst as well as a preparation and an application thereof. The catalyst MnWOx/TiO2-SiO2 takes a TiO2-SiO2 composite oxide prepared with a sol-gel method as a carrier and MnWOx supported with a liquid phase deposition method as an active component, wherein the mass of the active component MnWOx is 5%-30% of the total mass of the catalyst, themass of the carrier TiO2-SiO2 composite oxide is 70%-95% of the total mass of the catalyst, and the mass of SiO2 in the carrier is 1%-50% of the total mass of the carrier; the catalyst has the NO conversion rate being 90% or above and the N2 selectivity being 90% or above at the temperature window of 170-350 DEG C. The catalyst MnWOx/TiO2-SiO2 has good sulfur resistance during working in sulfur-containing flue gas and can be used for selective catalytic reduction denitration under the lower temperature condition.
