Abstract

PURPOSE: To convert a pitch-like material to low-molecular materials, and to solubilize the toluene-insoluble component, by hydrogenating a pitch-like material cntaining large amount of toluene-insoluble component in the presence of a specific catalyst.
CONSTITUTION: A pitch-like material having a toluene-insoluble content of ≥10wt% and a softening point of 50W400°C (e.g. the material obtained by the solvent extraction of coal) is dispersed in an aromatic medium oil (e.g. liquefied coal oil), and the slurry is hydrogenated at 350W480°C under a hydrogen pressure of 30W350kg/cm2 in the presence of a catalyst having a specific surface area of ≥10m2/g, a pore volume of ≥0.2ml/g, and an average pore diameter of 50W 500Å and obtained by supporting a hydrogenation-active metal component (e.g. iron) to a non-acidic porous carrier (e.g. magnesia silicate such as sepiolite).
