Abstract FCC slurry oil (SO) is an important and yield-rich by-product of the FCC process, which can be regarded as the raw material of high-value-added carbonaceous products due to its abundant concentration of aromatic components, but essential pretreatments and purifications for SO are required before carbonization to eliminate the adverse factors. Appropriate sequential pretreatments aimed at achieving the high-value utilization of SO have been developed, and two-dimensional gas chromatography coupled with time-of-flight mass spectrometry (GC × GC-TOFMS), Fourier transform infrared spectroscopy (FTIR) and nuclear magnetic resonance (1H NMR, 13C NMR) were implemented for the systematical properties analyses of SO and its derivatives after sequential pretreatments. Polarized-light microscope, scanning electron microscope (SEM) and X-ray diffraction (XRD) were used to evaluate the microstructures and microcrystal parameters of intermediate species and final products during carbonization. Through the varying degrees of sequential pretreatments, the comprehensive properties of feedstocks were improved gradually which further led to the diverse development of carbonaceous mesophase at the early stage of carbonization. Furthermore, ordinary or superior needle coke can be synthesized from the obtained oil samples during sequential pretreatments. The synthesized needle coke had suitable performance for the application in anode material of lithium-ion batteries.

用于制备高价值固体碳材料原料的 FCC 油浆样品的顺序预处理

摘要 FCC 油浆（SO）是 FCC 过程中重要且产率高的副产品，由于其芳香组分含量丰富，可作为高附加值碳质产品的原料，但必须进行预处理。碳化前需对SO进行提纯，以消除不利因素。已开发出旨在实现 SO 高价值利用的适当顺序预处理，以及二维气相色谱结合飞行时间质谱 (GC × GC-TOFMS)、傅里叶变换红外光谱 (FTIR) 和核磁共振（1H NMR，13C NMR）用于顺序预处理后SO及其衍生物的系统特性分析。偏光显微镜，使用扫描电子显微镜 (SEM) 和 X 射线衍射 (XRD) 评估碳化过程中中间物种和最终产物的微观结构和微晶参数。通过不同程度的序贯预处理，原料的综合性能逐渐提高，进一步导致炭化初期碳质中间相的多样化发展。此外，在连续预处理过程中，可以从获得的油样合成普通或优质针状焦。合成的针状焦具有适用于锂离子电池负极材料的性能。通过不同程度的序贯预处理，原料的综合性能逐渐提高，进一步导致炭化初期碳质中间相的多样化发展。此外，在连续预处理过程中，可以从获得的油样合成普通或优质针状焦。合成的针状焦具有适用于锂离子电池负极材料的性能。通过不同程度的序贯预处理，原料的综合性能逐渐提高，进一步导致炭化初期碳质中间相的多样化发展。此外，在连续预处理过程中，可以从获得的油样合成普通或优质针状焦。合成的针状焦具有适用于锂离子电池负极材料的性能。
