| 摘 要： | 以HZSM-5为载体，用钼酸铵和磷酸二氢铵做钼源和磷源，硝酸锆作为锆源，采用共沉淀法制备了氧化态前体，采用程序升温还原法制备出了负载型磷化钼催化剂，进行了XRD、 和BET表征。在反应温度360 ℃、压力2.5 MPa、空速1.0 h-1、氢油体积比400:1的条件下，在小型固定床反应器上进行全馏分FCC汽油的芳构化反应。考察了催化剂中，MoP负载量、ZrO2负载量和不同钼磷摩尔比对芳构化性能的影响。结果表明，当催化剂中钼的质量分数为25 %、ZrO2的质量分数为10 %、n（Mo）：n（P）=1:1.5、反应温度为360 ℃时，催化剂芳构化活性最佳。液相产品中芳烃质量分数为38.37 %，烯烃质量分数为18.11 %，液体收率为92.52 %。

| Abstract: | Using HZSM-5 zeolite as support,ammonium molybdate,ammonium biphosphate and zirconium nitrate as the sources of molybdenum,phosphorus and zirconium respectively,an oxidized precursor was obtained by co-precipitation method,and followed by temperature-programming reduction(TPR) to form MoP/ZrO2/HZSM-5 catalyst.The prepared catalysts were characterized by XRD and BET methods.The aromatization tests of full-range FCC naphtha over MoP/ZrO2/HZSM-5 catalysts were conducted on a small-scale fixed bed reactor to in... |
