中文摘要 | 本文說明重油加氫脫硫觸媒在試驗工場的測試過程,使用含金屬量高的重質油 料可以加達老化測試,縮短觸媒的壽命測試時間達原有的1/3;在整理測試數據上以二次動 力學來代表反應活性,依不同的觸媒衰退模式導出線性關係式,觸媒上的金屬沉積量是反 應活性的指標,使用Ash-layer Diffusion Control的數學模式可以方便地處理測試數據 ,油料的反應性也由實驗及計算方法求得。利用此模式估算得到Topsoe觸媒操作特性曲線 與原廠商文獻報導結果相當吻合,可見試驗工場測試數據與資料分析方法皆有相當的可信 度。依此方法已測試六種商業觸媒並比較具優劣。 試驗工場測試數據已在多方應用,如反應活性參數了估算觸媒在實際應用時所需的反 應溫度,與KOR#3RDS現場操作反應溫度比較亦相當接近,可見試驗工場數據可以用於現場 操作溫度建議,並提出操作策略來充分利用各觸媒床活性;在比較各商用觸媒於相同操作 周期時的產品產值,可以列出觸媒系統的優劣順序;HDM/HDS使用比例應隨工場而異, KOR#3RDS需要50%HDM,TOR#2RDS則需70%HDM;在RDS/RFCC串聯效益考量下,RDS操作於90- 95%脫硫率最適當。 |
英文摘要 | Pilot plant testing procedures on resid desulfurization catalyst system are described. An accelerated life test method using a heavier feed with higher metal contents is established. A second order kinetics is applied for data analysis. Metal deposition on catalyst (MOC) is considered to be the main cause for catalyst deactivation. Ash-layer diffusion control model can be easily applied for data analysis to obtain reaction parameters. These parameters have been used to predict catalyst performance curve that has an excellent fitting comparison to published data. Kinetic data obtained from pilot plant test has also been used to correlate real RDS plant operation data successfully. Based on the same operation cycle requirement , comparison among several commercial catalyst systems in term of its economic impact is possible. Depending on the plant catalyst inventory, a suitable HDM/HDS ratio has be found for each plant with 50% HDM for KOR #3RDS and 70% HDM for a much smaller plant TOR #2RDS. For the overall consideration of RDS/RFCC operation, RDS unit operating at 90-95%HDS severity is found to be economically feasible. |
