Abstract Fe/attapulgite powder (AP), Ni/AP, and Fe-Ni/AP were prepared by thermally decomposing iron pentacarbonyl (IPC), nickel tetracarbonyl (NTC), and different molar ratios of IPC to NTC onto AP in ethoxyethane, respectively. Their activities for the catalytic hydrocracking of di(1-naphthyl)methane (DNM) were compared under the same conditions. As a result, the activity of Fe-Ni-S/AP (Fe:Ni = 2:1) for DNM hydrocracking is significantly higher than that of other catalysts used. DNM conversion is near 100% over Fe-Ni-S/AP with Fe:Ni = 2:1. Over the catalyst, H2 can be effectively split to H , which attacks the ipso-position of DNM to cleave the Car-Calk bridged bond in DNM. Naomaohu lignite was subjected to thermal dissolution/ethanolysis in ethanol to afford soluble portion 1 (SP1, yield 56.0%) and residue 1 (R1) followed by non-catalytic hydroconversion (NCHC) and catalytic hydroconversion (CHC) of SP1 and R1 at 300 °C using Fe-Ni-S/AP with Fe:Ni = 2:1 as the catalyst to afford SPNCHC, SPCHC, SP2 (yield 2.3%), and SPII (yield 11.2%). According to gas chromatography/mass spectrometric analysis, arenes are the most abundant in SPCHC, accounting for 21.9%, while the most abundant group component in SPNCHC are non‑nitrogen ketones, accounting for 20.0%.

活性可回收双金属催化剂催化加氢转化脑毛胡褐煤衍生物

摘要 通过将五羰基铁 (IPC)、四羰基镍 (NTC) 和不同的 IPC 与 NTC 摩尔比分别在 AP 中的乙氧基乙烷中热分解制备 Fe/凹凸棒石粉 (AP)、Ni/AP 和 Fe-Ni/AP。 . 在相同条件下比较了它们对二（1-萘基）甲烷（DNM）催化加氢裂化的活性。因此，Fe-Ni-S/AP (Fe:Ni = 2:1) 的 DNM 加氢裂化活性明显高于其他催化剂。DNM 转化率比 Fe-Ni-S/AP 接近 100%，Fe:Ni = 2:1。在催化剂上，H2 可以有效地分裂为 H，它攻击 DNM 的同位以裂解 DNM 中的 Car-Calk 桥键。将脑毛胡褐煤在乙醇中进行热溶解/乙醇分解，得到可溶性部分 1（SP1，产率 56. 0%) 和残留物 1 (R1)，然后在 300 °C 下使用 Fe-Ni-S/AP 和 Fe:Ni = 2:1 作为 SP1 和 R1 的非催化加氢转化 (NCHC) 和催化加氢转化 (CHC)催化剂以提供 SPNCHC、SPCHC、SP2（产率 2.3%）和 SPII（产率 11.2%）。根据气相色谱/质谱分析，SPCHC 中芳烃含量最高，占 21.9%，而 SPNCHC 中含量最多的基团组分是非氮酮，占 20.0%。
