| 摘 要： | 采用三苯基砷和三乙基砷作为砷化物配制高砷模拟油,用于对CoMo/Al2O3加氢脱硫催化剂进行强制积砷中毒处理,采用BET,XRD,XRF,Py-IR等分析手段对砷中毒前后催化剂的物化性质进行表征,对中毒前后催化剂的加氢活性进行评价,并对砷中毒催化剂的失活温度进行考察。结果表明:砷化物使加氢催化剂的强酸位消失,B酸位和L酸位总量明显降低,催化剂活性位减少,造成催化剂加氢活性降低。

| Abstract: | The influence of arsenic compounds on the HDS activity of CoMo/Al2O3 catalyst was tested using a model oil with high content of Triphenyl arsenic or Triethyl arsenic as arsenic source. The catalyst was conducted the spiked treatment of arsenic. XRF, BET, XRD and Py-IR were used to characterize the physicochemical properties of CoMo/Al2O3catalysts before and after arsenic poisoning. The hydrogenation activity of CoMo/Al2O3 before and after arsenic poisoning as well as the deactivation temperature of the fouled catalyst was evaluated. The results indicated that after arsenic poisoning, the hydrogenation activity of CoMo/Al2O3 decreased significantly due to the loss of B and L acidities of the catalysts. |
