Abstract

A process for calcining green coke containing combustible volatile matter in at least two stages, whereby in a first stage the green coke is heated in a furnace to a temperature of between 750 DEG C and 1000 DEG C and in a second stage in a second furnace to a temperature of between 1200 DEG C and 1600 DEG C, characterized in that the heating in the first stage is carried out with a controlled heat-up rate of less than 60 DEG C/min in the temperature range of between 600 DEG C and 800 DEG C, whereby said heating up is achieved by hot combusted volatile matter, which is obtained by withdrawing the released volatile matter from the first stage, burning said volatile matter outside the first stage and recycling the burnt volatile matter to the first stage.
