PURPOSE: To improve the yield of an oil component, by separating thermal reforming reaction products into gas, light oil and heavy residual oil, and subjecting the residual oil to a gravity precipitation treatment to recover a liquid contg. neither heavy metals nor solid.
CONSTITUTION: Raw heavy oil fed through a line 1 and carbonaceous solid particles fed through a line 3 are introduced into a thermal reforming apparatus 7. Gas in the resulting thermal reforming reaction products is separated and recovered in a gas-liquid separator 13, and light oil is recovered in a vacuum distillation column 17. The resulting heavy residual oil together with a solvent fed through a line 23 is fed to a gravity precipitation treatment device 27. The resulting supernatant liquid contg. neither heavy metals nor solid is fed to a distillation column 31. The solvent is recovered from a line 33 and the liquid is recovered from a line 35. The solid residue is fed to a distillation column 39. The solvent is recovered from a line 41 and the solid is discharged from a line 43.
