Abstract
PURPOSE: To achieve an advantageous and easy industrial production of high- quality carbonaceous materials by removing insoluble precipitates that produce in mixture liquid of coal heavy oil, specific petroleum heavy oil, and solvent, then by removing solvent.
CONSTITUTION: Coal heavy oil, petroleum heavy oil or petroleum cracked residue oil, and solvent are mixed, and insoluble precipitates produced in the mixture is removed. Then solvent is removed to produce heavy oil. This process makes use of petroleum heavy oil or petroleum cracked residue oil having atomic ratio of hydrogen to carbon (H/C) of 1.2 or more, Conradson carbon content being 1% or more, and b.p. being 200°C or more, and solvent that can be dissolved by both heavy oils of coal and petroleum and that has b.p. 200°C or less. The coal heavy oil employed includes by-product coal tar in dry distillation of coal, heavy part product in coal liquefaction.
