Abstract Untreated and mildly hydrotreated pyrolysis derived liquids are evaluated in FCC processing by co-feeding with vacuum gas oil (‘VGO’). Pyrolysis liquids (PLs) applied are from the Empyro plant in the Netherlands. The treated PLs are produced by BTG employing novel bimetallic Ni-based catalyst (Picula), at 200 bar hydrogen pressure and two temperatures, 120 °C and 225 °C. A pilot scale riser setup (riser: I.D. = 7 mm, length = 9 m; combustor: I.D. = 78 mm) is employed to process the liquids with VGO. The riser is operated at a riser outlet temperature of 525 °C, atmospheric pressures and Cat-to-Oil (‘C/O’) ratio ranging from 5 to 8. Co-processing ratios are kept constant at 10:90 (PLs:VGO). The most relevant observations compared to processing of only VGO are: – At all C/O ratios, the conversion observed in the co-processing tests is higher. – The yield of coke, dry gas and LPG in all co-processing tests is lower. – At such high substitution levels co-processing crude PL shows a decrease in the gasoline yield and slightly higher yield of LCO and bottoms. – The treated bio-liquids yield similar levels of gasoline and LCO. During crude PL co-processing CO and CO2 are noted, and a decrease in H2 yield is found compared to pure VGO. Renewable carbon is observed in the liquids obtained in both co-processing crude PL and stable pyrolysis oil (SPO), while the mild hydrotreating steps are more effective.

在中试规模的 FCC 立管装置中协同处理原油和加氢处理热解液和 VGO

摘要 未经处理和轻度加氢处理的热解衍生液体在 FCC 加工中通过与真空瓦斯油 ('VGO') 共同进料进行评估。应用的热解液 (PL) 来自荷兰的 Empyro 工厂。经处理的 PL 由 BTG 使用新型双金属镍基催化剂 (Picula) 在 200 bar 氢气压力和两个温度（120°C 和 225°C）下生产。采用中试规模的立管装置（立管：ID = 7 mm，长度 = 9 m；燃烧器：ID = 78 mm）用 VGO 处理液体。立管在 525 °C 的立管出口温度、大气压和 5 到 8 的催化剂油 ('C/O') 比范围内运行。协同处理比保持恒定在 10:90 (PLs: VGO）。与仅处理 VGO 相比，最相关的观察结果是： – 在所有 C/O 比率下，在协同处理测试中观察到的转化率更高。– 在所有协同处理测试中，焦炭、干气和液化石油气的产量较低。– 在如此高的替代水平下，协同处理原油 PL 会导致汽油收率下降，而 LCO 和残渣的收率略高。– 处理过的生物液体产生相似水平的汽油和 LCO。在粗PL协同处理CO和CO2过程中，发现与纯VGO相比，H2产率有所降低。在协同处理原油 PL 和稳定热解油 (SPO) 中获得的液体中观察到可再生碳，而温和的加氢处理步骤更有效。– 处理过的生物液体产生相似水平的汽油和 LCO。在粗PL协同处理CO和CO2过程中，发现与纯VGO相比，H2产率有所降低。在协同处理原油 PL 和稳定热解油 (SPO) 中获得的液体中观察到可再生碳，而温和的加氢处理步骤更有效。– 处理过的生物液体产生相似水平的汽油和 LCO。在粗PL协同处理CO和CO2过程中，发现与纯VGO相比，H2产率有所降低。在协同处理原油 PL 和稳定热解油 (SPO) 中获得的液体中观察到可再生碳，而温和的加氢处理步骤更有效。
