A hierarchical porous zeolite Y (HPZY) supported Ni–Co catalyst was prepared by pyrolyzing nickel tetracarbonyl and using modified deposition-precipitation to highly disperse Ni–Co nanoparticles onto HPZY. Hecaogou subbituminous coal was effectively ethanolyzed to obtain ethanol-soluble portion (ESP_E) in a high yield (21.2%). Sequentially, ESP_E was subjected to the deep hydroconversion (DHC) over prepared Ni_10%-Co_3%/HPZY at 150 °C under 4 MPa of initial hydrogen pressure for 24 h in n-heptane to produce deeply hydroconverted ethanol-soluble portion (ESP_DHC). All the group components in ESP_E, including arenes (53.3%), oxygen-containing organic compounds (24.4%), and nitrogen-containing aromatics (2.3%) were completely converted to chain alkanes (CAs, 36.8%), cyclanes (39.2%), and hydroarenes (24.0%). In addition, the hydroisomerization of CAs and hydroreforming of aromatic rings (ARs) in ESP_DHC are predominant over Ni_10%-Co_3%/HPZY with more accessibility of active sites under mild conditions. Ni_10%-Co_3%/HPZY with suitable acidity and highly dispersed Ni–Co nanoparticles can effectively activate H₂ to H⋯H and further heterogeneously split H⋯H to H⁺ and H⁻. H⋯H and H⁺ transfer plays crucial roles in the DHC of ESP_E. Correspondingly, the related mechanisms are evidenced by the DHC of 2,2′-oxydinaphthalene (ODN) over Ni–Co/HPZY. Ni_10%-Co_3%/HPZY maintains high activity for the DHC of ODN under mild conditions after 4 recycles.

通过热解四羰基镍并使用改进的沉积-沉淀法将 Ni-Co 纳米颗粒高度分散到 HPZY 上，制备了分级多孔沸石 Y (HPZY) 负载的 Ni-Co 催化剂。对河草沟次烟煤进行有效乙醇化，以高收率（21.2%）获得乙醇可溶部分（ESP _E）。随后，ESP _E在 150 °C 和 4 MPa 的初始氢气压力下在正庚烷中对制备的 Ni _10% -Co _3% /HPZY 进行深度加氢转化 (DHC) 24 小时，以产生深度加氢转化的乙醇可溶部分(ESP _DHC )。ESP _{E 中的}所有组组件，包括芳烃（53.3%）、含氧有机化合物（24.4%）和含氮芳烃（2.3%）完全转化为链烷烃（CAs，36.8%）、环烷烃（39.2%）和氢芳烃（24.0%） %）。此外，ESP _DHC中CA 的加氢异构化和芳环 (AR) 的加氢重整优于 Ni _10% -Co _3% /HPZY，在温和条件下更容易接近活性位点。Ni _10% -Co _3% /HPZY 具有合适的酸度和高度分散的 Ni-Co 纳米粒子可以有效地将 H ₂活化为 H⋯H，并进一步将 H⋯H 异质分裂为 H ⁺和 H ^-。H⋯H 和 H ⁺转移在 ESP _E的 DHC 中起着至关重要的作用。相应地，2,2'-氧化二萘（ODN）在Ni-Co/HPZY上的DHC证明了相关机制。Ni _10% -Co _3% /HPZY 在温和条件下在 4 次循环后保持对 ODN 的 DHC 的高活性。
