| 摘 要： | 按照国产S101型钒催化剂的活性组分配方制备了由3种不同组成的NZP族磷酸盐载体负载的钒催化剂,通过XRD、BET法对催化剂的物相结构、比表面积和孔结构进行了表征,在小型固定床反应器中对催化剂进行了活性评价。结果显示,载体的化学组成对钒催化剂的活性有显著影响,其中,组成为KZr2(PO4)3的NZP族载体较为适合作为钒催化剂的侯选载体材料。

| Abstract: | The vanadium catalysts supported by three different composition phosphate carriers belonging to NZP family were prepared by wet-blend method,and their active composition is the same as that of home-made S101 vanadium catalyst.The phase,specific surface area and pore structure of these catalysts were characterized by X-ray diffraction(XRD) and BET methods,and their activities were also evaluated in a small fitted-bed reactor.The results show that the chemical composition of the carriers has important influence on the activity of vanadium catalysts.KZr_2(PO_4)_3 is fit for being the candidate carrier of vanadium catalysts. |

| Keywords: | carrier belonging to NZP family vanadium catalyst activity |
