英文摘要 | 本文研討重油加氫反應模式的建立。觸媒活性的衰退主要應是因為金屬累積觸媒 上在反應時活性的衰退即以提高反應溫度來補償。不同的觸媒衰退模式都能加以線性化來測 試是否合理,本文提出灰燼層擴散控制模式可以相當成功地來分析試驗工場測試數據。 在觸媒壽命測試上可以使用含金屬量較高的油料做加速老化壽命測試,同時亦有時改用不同 油料做油料反應性測試,利用觸媒衰退數學模式及非線性混合律來得到各油料的反應常數, 活化能以及觸媒最大沈積量,由這些參數即可預測觸媒操作特性曲線,在與廠商文獻報導比 較結果非常相近,可見試驗工場測試數據及資料分析方法皆有相當的可信度。 characteristic temperature curve using derived linear plots. The proposed model based on the diffusion limitation inside the catalyst has been found to be quite successful in correlating pilot plant data. An accelerated catalyst life test can be accomplished by using a heavier feed with higher metal concentrations and higher flowrate. Feed reactivity tests are also performed periodically during such a life test run using feedstocks from different sources.With the model and a non-linear mixing rule for feed reactivity calculation, parameters such as activation energy, reaction constant and maximum metal loading etc. are determined. These parameters can be used to predict catalyst performance. An excellent fitting comparison to published data is an indication of the success of this pilot testing program and data analysis method. |
