The technical and economic indices of operation of pitch coke divisions are dependent upon the characteristics of the feedstock and the stability of its quality, the oven charging and heating regimes, and the condition of the equipment. In Soviet technology for production of electrode pitch coke the feedstock used is high-temperature pitch (HTP). Investigations conducted by coking plants and institutes showed that the following composition of the coking feedstock is optimal: substances insoluble in quinoline, 28 to 40%; substanes insoluble on toluene, 47 to 50%; substances soluble in toluene but insoluble in isooctane, 20 to 25%; substances soluble in toluene and isooctane, 25 to 30%. This composition provides the necessary ratio of components for normal coking conditions and provides a 65% yield of coke cake. In addition, for production of HTP of this composition, in addition should be used heavy pitch distillates and coal tar should be used. Discussed are problems related to the preparation and charging of the feedstock and the state of the technology.
