| 摘 要： | 采用溶胶-凝胶法制备了TiO2-ZrO2复合载体，并用共浸渍法制备负载型MoP/TiO2-ZrO2催化剂，通过原位还原技术对催化剂进行还原处理后，在连续固定床反应器上进行活性评价。结果表明， TiO2和ZrO2物质的量比以及Mo负载量对催化剂活性有较大影响，当n(Ti)∶n(Zr)=4∶1和Mo负载质量分数为20%时，MoP/TiO2-ZrO2催化剂的加氢脱氮效果最好，并且TiO2-ZrO2复合载体比TiO2-Al2O3复合载体的活性提高12.4个百分点。

| Abstract: | TiO2-ZrO2 mixed supports were prepared by solgel method and used in preparation of MoP/TiO2ZrO2 catalysts by coimpregnation. Hydrodenitrogenation(HDN) activity of the catalysts was tested in a fixed bed reactor after insitu reduction. The results showed that titaniumtozirconium molar ratio and Mo loadings had remarkable influence on activity of the catalysts. Optimal HDN activity was attained over MoP/TiO2-ZrO2 catalysts under n(Ti)∶n(Zr) of 4∶1 and Mo loadings of 20%(mass fraction). HDN rate of the catalysts supported on TiO2-ZrO2 was 12.41% higher than that on TiO2-Al2O3. |
