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

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.

         5 . A process for producing coke, the process comprising:
 a step of extracting a solvent deasphalted pitch that can be used as a caking additive for coke production from a residue comprising 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 extracting 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, and   a step of producing a coke by performing dry distillation of a raw material coal for coke production that comprises the solvent deasphalted pitch.   
     
     
         6 . The process for producing coke according to  claim 5 , wherein the raw material coal for coke production comprises 0.5 to 10% by mass of the solvent deasphalted pitch. 
     
     
         7 . The process for producing coke according to  claim 5 , wherein the raw material coal for coke production comprises 10 to 50% by mass of a non-caking coal or slightly caking coal. 
     
     
         8 . The process for producing coke according to  claim 6 , wherein the raw material coal for coke production comprises 10 to 50% by mass of a non-caking coal or slightly caking coal.
