Abstract
PURPOSE: To liquefy coal by using petroleum heavy oil which ahs good performance and can be stably supplied in large quantities at low cost by a method wherein coal powders are slurried by using a fraction obtd. by partially nucleus-hydrogenating recycle oil and the slurry is heat-treated under pressure.
CONSTITUTION: Petroleum is catalytically cracked at a temp. of not less than 400°C by using silica and/or alumina. Amoung the resulting products, a fraction (recyle oil) having a boiling range of 200W450°C is used. Aromatic nuclei in the fraction are partially nucleus-hydrogenated in the presence of a catalyst for hydrogenation. The resulting partially hydrogenated oil alone or a mixt. thereof with pertroleum heary oil, or liquid material resulting from the above process is used as solvent. 1W10pts.wt. of this solvent is mixed with 1pts.wt. of coal powders to form slurry. The slurry is heat-treated at a temp. of 300W500°C and at a pressure within the range of normal pressure to 200kg/cm2.G for 0.2W5hr.
