Abstract
The present invention relates to a method for producing an impregnated pitch from a petroleum-based raw material and to an impregnated pitch produced using the same, and when the method for producing an impregnated pitch according to the present invention is used, it is possible to produce an impregnated pitch having a high carbonization yield (40 wt % or more) and low quinoline insoluble matter (QI, 2% or less) for improving efficiency of an impregnation process from a petroleum-based raw material. Therefore, when an impregnation process is applied to a carbon compact by using the impregnated pitch according to the present invention, it is possible to remarkably reduce micropores inside the carbon compact, and to produce a carbon compact having physical properties such as excellent electrical conductivity and mechanical strength.
