摘　　要：为了脱除油品中的碱性氮化物,以Zr(NO_(3))_(4)和Fe(NO_(3))_(3)为金属源,(NH_(4))_(2)S_(2)O_(8)作为浸渍液,采用共沉淀法制备出固体超强酸催化剂S_(2)O_(8)^(2-)/Fe_(2)O_(8)、S_(2)O_(8)^(2-)/ZrO_(2)和S_(2)O_(8)^(2-)/Fe_(2)O_(3)-ZrO_(2)。通过XRD、FT-IR、NH_(3)-TPD、BET对催化剂进行表征。结果表明,经过掺杂后,催化剂的比表面积及孔径增大,并且增强了催化剂酸性。将这3种催化剂在不同工艺条件下进行考察,找到了S_(2)O_(8)^(2-)/Fe_(2)O_(3)-ZrO_(2)催化剂的最佳脱碱性氮条件:当碱性氮化物含量为178×10^(-6)时,催化剂用量5mg·mL^(-1),反应时间15min,反应温度50℃,氧化剂加入量与模拟油体积比为1∶20时,脱碱性氮率达到99%。In order to remove basic nitrides in oil products,solid superacid catalysts S_(2)O_(8)^(2-)/Fe_(2)O_(8)、S2O28-/ZrOand S_(2)O_(8)^(2-)/Fe_(2)O_(3)-ZrO_(2)were prepared by coprecipitation method using zirconium nitrate and ferric nitrate as metal sources and ammonium persulfate as impregnation liquid.By characterizing the catalyst,the results show that:S_(2)O_(8)^(2-)/Fe_(2)O_(3)-ZrO_(2)catalyst has higher acidity.This catalyst was investigated under different process conditions,and the best denitrification conditions for the S_(2)O_(8)^(2-)/Fe_(2)O_(3)-ZrO_(2)catalyst were found:when the basic nitride content is 178×10^(-6),the catalyst dosage is 5mg·mL,the reaction time is 15min,and the reaction temperature is 50℃,when the ratio of the oxidant addition to the simulated oil volume is 1∶20,the denitrification rate reaches 99%.
