Title:
THERMAL REFORMING OF HEAVY OIL
Document Type and Number:
Japanese Patent JPS60106885
Kind Code:
A
Abstract:

PURPOSE: To improve the yield of a light oil component, by separating thermal reforming reaction products into gas, light oil and heavy residual oil, subjecting at least part of the residual oil to a gravity precipitation treatment and adding the resulting heave dissolved matter to raw heavy oil for reuse.

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 recovered in a gas- liquid separator 13 and light oil is recovered in a vacuum distillation column 17. At least part of the resulting heavy residual oil together with a solvent fed through a line 23 is fed to a gravity precipitation treatment device 27 to recover a liquid contg. neither heavy metals nor solid (the solid residual is fed to a distillation column 41 and the solvent is recovered from a line 43). Said liquid is fed to a distillation column 33, the solvent is recovered and the havy dissolved matter is recycled through a line 29 to add it to the raw heavy oil.
