Abstract

The refining of coal tar by hydrogenation is considered. In this process, nanoheterogeneous Ni-based catalysts may expediently be produced in situ from precursors in the reaction medium. The yield of needle coke in complete coal processing with recirculation of the residue at the coking stage is found to be 50–55%. That is 1.5 times the industrial yield in the coking of pitch.

纳米多相硫化镍催化剂下加氢精制煤焦油

摘要

考虑通过氢化精制煤焦油。在该方法中，可以方便地从反应介质中的前体原位制备纳米多相的镍基催化剂。在焦化阶段完成残渣再循环后，在完整的煤炭加工过程中，针状焦的产率为50-55％。这是沥青焦化工业产量的1.5倍。
