<p>The invention relates to a process and installation for producing electrometallurgical coke and calcined petroleum coke. According to the invention, the process consists in bringing coal and petroleum coke into direct contact and in counter-flow with a stream of flue gases, distributed across the entire surface of coal granules with sizes from 5 to 30 centimeters or petroleum coke, with sizes from 5 to 40 mm, resulting from the combustion of 20 ... 30 % of discharged gases or by the combustion of methane gas in the material layer at a temperature of 900 ... 1, 000A C for the degassing process or at a temperature higher than 1, 600A C for the calcining process for 6 to 7 hours.</p> |
