Process for continuously coking hard coal pitch

摘要

1. A process for continuously coking hard coal pitch to produce a calcinated formed coke comprised of the following process stages : - low-temperature carbonization of the approx. 300 degrees C hot hart pitch being employed to produce a low-temperature coke with a temperature of less than 600 degrees C, - briquetting of low-temperature coke with admixture of hot binder hard pitch, - calcination of briquettes at temperatures of up to approx. 1.400 degrees C, and - subsequent cooling of briquettes, characterized in that the calcination is carried out in an indirectly fired vertical chamber slot-type oven and that a rich gas is generated which after cleaning and cooling serves for indirect heating at the low-temperature carbonization stage and/or calcinating stage or for other purposes.
