“…Transition metals, especially noble metals, can catalyze the hydrogenation of ARs under mild conditions by catalyzing the formation and transfer of biatomic active hydrogen. , Unfortunately, despite the prominent catalytic activities and extraordinary selectivities of noble metals, the exorbitant price and sensitivity to heteroatoms restrict the application of such catalysts. , Metal sulfides (MSs) and metal oxides (MOs), which are relatively cheap and chemically stable, could stimulate the transfer of hydrogen radical followed by subsequent catalytic hydrogenations of ARs. − Nevertheless, the actual use of MSs remain rigorous despite the disadvantages of product contamination and equipment surface corrosion. , MOs suffer a long residence time to perform deep hydrogenation of ARs. , Hence, there is an urgent need to develop effective and reliable catalysts to eliminate these disadvantages.…”

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 hightemperature 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 positiveion 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 N 3 O x (x = 0−2) class species are predominant in SP NCHC , while the RAs of hydrocarbons, N 1 O 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.
