PRODUCTION OF POWDERY ARTIFICIAL GRAPHITE

摘要

PURPOSE: To provide a producing method of powdery artificial graphite capable of producing through an industrially advantageous simple process and having excellent graphitized degree by using exceedingly cheap raw material. CONSTITUTION: In this method, a caking material as a still residue after partially heat-decomposed a vacuum residue generated in a crude oil purifying process by a heated steam is used as a raw material. The raw material is coked at a temperature able to coke (500-1200 deg.C), resultant coked material is further graphitized at a graphitizable temperature (2300-3000 deg.C). A d(002) after the graphitization is 3.360±0.006Å.
