摘要：To achieve full utilization of ethylene tar (ET), a novel chemical crosslinking-carbonization process was developed in this work to successfully convert the residual aromatic components (denoted as LFET), remained from catalytic hydroprocessing of ET, into carbon precursors with higher molecular weight and crosslinking degree, followed by conversion into high value-added carbon materials. Initially, the feasibility of converting LFET into carbon precursors was theoretically confirmed via reaction path investigation by combining density functional theory (DFT) simulation and experiments, in which LFET was successfully transformed into carbon precursors with yield of 75.55%. To assess the feasibility of converting these precursors into carbon, the synthesized precursors were subsequently carbonized into carbon materials. These carbons exhibited pseudo-graphitic phase and graphitic-like phase, accounting for 13.19-28.44% and 71.56-85.06%, respectively. Furthermore, aromatic hydrocarbons with aliphatic side-chains, high planarity and a greater number of fused rings from LFET were easily converted into carbon materials with highly ordered microcrystalline structures and low d-spacing. The obtained carbons presented significant potential as anode materials for lithium-ion storage. Hence, the LFET was successfully converted into carbon materials via this novel process, providing a novel strategy for high add-value utilization of LFET and thereby achieving full utilization of ET.
