Co-Mo/γ-Al₂O₃ bimetallic catalyst was prepared by incipient wetness impregnation and the physicochemical properties were obtained by a series of characterization methods. The active components are mainly MoS₂ and Co-Mo-S existing on γ-Al₂O₃, the support. Meanwhile, the activity of catalyst in hydroconversion of four coal-related model compounds (CRMCs), dibenzyl ether, furan, thiophene and quinoline, was investigated. Hydroconversion products were analyzed by gas chromatography/mass spectrometry (GC/MS) and the possible reaction pathways were proposed according to the GC/MS data. Oxygen was removed from dibenzyl ether via the direct cleavage of C_alk-O bridge bond to produce benzylium cation followed by the combination with H⁻ to generate toluene. The hydroconversion of furan can be realized by the direct cleavage of C_ar-O bond and direct hydrogenation, respectively. For thiophene, H⁺ directly transferred to sulfur atom, leading to the cleavage of C_ar-S bond to produce H₂S and 1,3-butadiene, which abstracted active hydrogen to yield butane. Another indirect desulfurization pathway for thiophene is hydrogenating to form tetrahydrothiophene and C–S bond cracking to produce butane. Hydroconversion of quinoline started with either N-ring or benzene ring, and the first one was the main pathway.

的Co-Mo /γ-Al系₂ ö ₃的双金属催化剂是通过初始润湿浸渍制备，并通过一系列表征方法获得的物理化学性质。活性成分主要的MoS ₂和现有上的γ-Al共的MoS ₂ ö ₃，支撑。同时，研究了催化剂在四种与煤有关的模型化合物（CRMC），二苄基醚，呋喃，噻吩和喹啉的加氢转化中的活性。通过气相色谱/质谱（GC / MS）分析加氢转化产物，并根据GC / MS数据提出了可能的反应途径。通过直接裂解C _alk从二苄基醚中除去氧气-O桥键以产生benzylium阳离子，随后用H的组合^-来产生甲苯。呋喃的加氢转化可以分别通过C _ar -O键的直接裂解和直接氢化来实现。对于噻吩，H ⁺直接转移到硫原子上，导致C _ar -S键断裂，生成H ₂ S和1,3-丁二烯，后者提取出活性氢，生成丁烷。噻吩的另一种间接脱硫途径是加氢形成四氢噻吩和C–S键裂解生成丁烷。喹啉的加氢转化始于N环或苯环，第一个是主要途径。
