中文摘要 | 本研究使用FCC-SIM軟體,建立RFCC製程模擬技術,並採用FCC-SIM進料加氫模式,改變進料加氫程度,進行RFCC工場模擬。分析數據(GC-MS、NMR、HPLC)顯示重油經加氫處理後可以降低重油的金屬、硫和氮含量,同時降低焦碳前驅物(多環芳香烴和高沸點組成),以及增加汽油前驅物(單環芳香烴)。FCC-SIM預測結果顯示進料加氫程度改變ECAT的活性和選擇性,以及RFCC進料的碳結構組成,對RFCC工場轉化率、焦碳、燃料氣和塔底油產率影響很顯著。操作條件(CAT/Oil Ratio、再生器溫度和新鮮觸媒添加量)則因焦碳產率變化而改變。本研究結果顯示RFCC進料隨加氫程度提升(RDS工場反應激烈度提高)而變輕,使得RFCC工場效益增加,與RDS工場操作成本相比,模擬結果將協助煉油廠進行RDS工場和RFCC工場最適化操作的評估。 |
英文摘要 | The RFCC simulation technology was established in this study using FCC-SIM software. The hydrotreating severity of RFCC feedstocks is modeled by changing the parameter of hydroprcoessing severity in the FCC-SIM feed model. Hydrodesulfurization of FCC feedstocks removes some of the metals, sulfur and nitrogen contents of atmospheric residues, which improves RFCC ECAT activity and selectivity. Analytical data (GC-MS、NMR、HPLC) show that hydrotreating RFCC feedstocks reduces amounts of coke precursor (polyaromatics and high boiling point components) and generates more gasoline precursor (mono-aromatics). The prediction of FCC-SIM simulation shows that the ECAT properties and the carbon structure of the RFCC feedstock have a significant effect on conversion, coke, fuel gas and bottom oil yield. The operating conditions (CAT/Oil ratio, regenerator temperature, and fresh catalyst addition rate) vary with the change in coke yield. The results of this study show that the RFCC feedstocks become lighter and more valuable with increasing hydrotreating severity of a RDS unit. This study will assist the refinery in the optimizing integration of the RDS unit with the RFCC unit. |
