Process for producing caking additive for coke production and process for producing coke

摘要

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.

1. A caking additive for coke production consisting of a solvent deasphalted pitch, wherein the caking additive for coke production has a softening point within a range from 179 to 200° C., an amount of carbon residue within a range from 30 to 70% by mass, and an atomic ratio of hydrogen to carbon of not more than 1.2.
