| 摘 要： | 通过对反应前后的煤焦油加氢裂化催化剂进行表征与分析,研究影响中低温煤焦油加氢催化剂失活的原因,以煤焦油组分特点为依据,分别考察加氢裂化催化剂的活性元素、积炭、金属沉淀、分散度和中心酸性等对催化剂寿命的影响。结果表明,煤焦油加氢催化剂的失活原因主要为积炭失活、金属沉积和水热失活;催化剂中较低的金属钙含量、良好的水热稳定性及较低的L酸含量有利于催化剂寿命的提高。

| Abstract: | The reasons for deactivation of hydrocracking catalyst for coal tar hydrotreating process in mid-low-temperature was studied by analysis the characterization of catalyst before and after the reaction.Based on the characteristics of coal tar,the influence of active elements,carbon deposition,metal deposition,dispersion and central acidity on the catalyst life was studied.The results showed that carbon deposition,metal deposition and hydrothermal deactivation were the main reasons for the deactivation of hydrocracking catalyst.Good hydrothermal stability,low content of Ca and Lewis acid in catalyst favored prolonging the hydrocracking catalyst life. |
