Abstract
A continuous process for calcining coke comprises passing coke particles and an oxidant concurrently into a combustion zone under conditions such that only a minor portion of the coke is oxidized, e.g. 2 to 25%, preferably 5 to 10%, by weight. The oxidant is oxygen or an oxygen-containing gas, or fluorine or chlorine, or nitrogen dioxide, and temperatures in the combustion zone lie in the range 540 DEG to 1400 DEG C., preferably 815 DEG to 1360 DEG C. In the example illustrated, coke, which is preheated, e.g. by recycled gas, is fed downwardly into a retort to which the oxidant is delivered, the combustion zone being stabilized by regulating the volumes of the coke and oxidant. In another example, a stationary column of coke is supplied with air at the top, the combustion zone travelling up the column.
