Two attapulgite powder (AP)-supported nickel catalysts were prepared by thermally decomposing nickel tetracarbonyl onto AP in a laboratory (L-Ni/AP) and in a factory (F–Ni/AP). The Ni nanoparticles are successfully dispersed on AP without evident agglomeration and mainly exist on the surface of AP in crystalline form with a small part entering into the mesopores. The soluble portion from non-catalytic hydroconversion (SP_NCHC) and catalytic hydroconversion (SP_CHC) of a high-temperature coal tar (HTCT) in cyclohexane over L-Ni/AP (SP_CHC-L) and F–Ni/AP (SP_CHC-F) were analyzed with a gas chromatograph/mass spectrometer and a quadrupole exactive orbitrap mass spectrometer with an APCI source operating in positive-ion model. The results show that the distribution of group components detected in SP_NCHC are obviously different from that in either SP_CHC-L or SP_CHC-F. The relative content of non-substituted condensed arenes in SP_CHC is ca. 75.0%, while the non-substituted polycyclanes and non-substituted hydroarenes are dominant in SP_CHC-L and SP_CHC-F. The relative abundances (RAs) of N₃O_x (x = 0–2) class species are predominant in SP_NCHC, while the RAs of hydrocarbons, N₁O_x, and O_x (x = 1,2) class species in SP_CHC-L and SP_CHC-F are the most abundant. Both catalysts are active for removing heteroatoms from the HTCT and hydrogenating aromatics in the HTCT, while L-Ni/AP is more effective for catalyzing the hydrogenation of the aromatics.

两种凹凸棒粉负载镍催化剂上高温煤焦油的催化加氢转化

通过在实验室（L-Ni / AP）和工厂（F-Ni / AP）中将四羰基镍热分解到AP上，制备了两种由凹凸棒粉（AP）负载的镍催化剂。Ni纳米粒子可以成功地分散在AP上而没有明显的团聚，并且主要以晶体形式存在于AP表面，一小部分进入中孔。L-Ni / AP（SP _CHC-L）和F-Ni / AP（SP _CHC-L）上环己烷中高温煤焦油（HTCT）的非催化加氢转化（SP _NCHC）和催化加氢转化（SP _CHC）的可溶部分SP _CHC-F用气相色谱/质谱仪和具有正离子模型的APCI离子源的四极精确轨道质谱仪进行分析。结果表明，SP _NCHC中检测到的组成分的分布与SP _CHC-L或SP _CHC-F中的明显不同。SP _CHC中未取代的缩合芳烃的相对含量为ca。75.0％，而未取代的聚环烷烃和未取代的氢芳烃在SP _CHC-L和SP _CHC-F中占主导地位。N ₃ O _x（x = 0–2）类物种的相对丰度（RA）在SP _NCHC中占主导地位，而在SP _CHC-L和SP _CHC-F中，碳氢化合物的RA，N ₁ O _x和O _x（x = 1,2）类物质最丰富。两种催化剂都具有从HTCT中除去杂原子和在HTCT中氢化芳烃的活性，而L-Ni / AP对催化芳烃的氢化更有效。
