Abstract (en)

[origin: US4764318A] Coke for reactor graphite is produced continuously by coking a hard pitch with a softening point (K.-S.) above 130 DEG C. and a coking residue of at least 45% by weight in a rotary pipe furnace equipped with a moving device and subsequent calcination without intermediate cooling. The temperature of the inner wall of the indirectly heated furnace ranges from about 500 DEG to about 800 DEG C. The gases and vapors formed during the coking process are guided in countercurrent flow to the pitch.
