Preferred Label : coal-derived pitch coke;
IUPAC definition : The primary industrial solid carbonization product obtained from coal tar pitch mainly
produced in chamber or delayed coking processes.;
Scope note : coal-derived pitch coke, although it exhibits a pregraphitic microstructure, has often
a lower graphitizability than petroleum coke. fractions of coal tar pitches (obtained
by extraction or filtration) may form cokes with needle-like structures and have an
improved graphitizability. the usually lower graphitizability compared to petroleum
coke is due to an inhibition of mesophase growth because of chemical and physical
differences of the cokes.;
