Abstract

A process for producing a caking additive for coke production, the process including a step of extracting a solvent deasphalted pitch that can be used as a caking additive for coke production from a residue containing at least one of an atmospheric residue obtained by atmospheric distillation of a crude oil and a vacuum residue obtained by atmospheric distillation and vacuum distillation of a crude oil, wherein the extraction is performed using, as a solvent, a light reformate obtained by catalytic reforming a naphtha fraction that is fractionated from a crude oil by atmospheric distillation of the crude oil.
