Method for manufacturing artificial graphite from waste containing carbonaceous material

摘要

The present invention relates to a process for producing artificial graphite from wastes containing carbonaceous materials, comprising the steps of: preparing bunker A, bunker B, bunker C, marine gas oil, desat oil, petro-cokes, petroleum cokes, and mixtures thereof, is heat-treated at a temperature of 2000 ° C or higher to crystallize the carbon black contained in the waste to form a conductive material or It is a technical point to obtain artificial graphite usable as an active material. As a result, since the carbon black is present in a large amount in the waste, there is no need to carry out the carbonization process, and since the carbon black is present, the effect of reducing the raw material supply cost can be obtained without using the carbon precursor. In addition, since the cost of treating wastes is not consumed, it is very economical. In producing artificial graphite, soft carbon as well as hard carbon can be obtained together.
