    • PURPOSE: To synthesize in high yield a partially hydrogenated product from polycyclic aromatic compound, by hydrogenation, using a specific catalyst under specified conditions, of the nephthalene fraction-removed high-boiling fraction in coal tar as raw material.
      CONSTITUTION: Coal tar (sludge elimination-treated) is distilled to remove the light component up to absorption oil fraction to prepare a fraction with a boiling point ≥ca. 280°C. This fraction is subjected to hydrogenation under a hydrogen partial pressure 40W180kg/cm
      2 G at 300W420°C under an LHSV0.2W2.0hr
      -1 , using a catalyst with an average pore size ca. 80W180Å having the surface area corresponding to the pores of a size ≥35Å of ca. 100m
      2 /g or more, prepared by carrying on a carrier ca. 10W30wt% of Mo oxides and ca. 1W6wt% of Ni and/or Co oxides, thus obtaining the objective compound with a partial hydrogenation degree H
      β /H
      α ≥1.1 derived from
      1 H-NMR (H
      β is the quantity of hydrogen attributed to δ=1.0W2.0ppm in the product; H
      α being the quantity of hydrogen attributed to δ=2.0W4.2ppm).
