Zusammenfassung: | Coking of liquid hydrocarbons for production of carbon products. Apart from the production of metallurgical coke, hydrocarbon mixtures are carbonized especially in conversion of heavy petroleum fractions for production of gasoline and middle distillates; petroleum coke is then obtained. In addition, residues having a high carbon content from petrochemical, oil refinery, and coal upgrading sources are also transformed into high‐quality cokes. The most important process for coking of petroleum‐ and coal‐derived hydrocarbons is delayed coking; in addition, horizontal chamber coking is also employed for coal tar pitch. The principal applications of high‐quality coke products are block‐ and Söderberg anodes for aluminium production, additives and carburizer for the iron and steel industry, graphite products for electrosteel manufacture, and carbon products for special electrolytic processes, chemical plant construction, and electrical engineering. Delayed coking of hydrocarbon mixtures will become increasingly important owing to the modest investment necessary compared to other conversion methods and to the growing share of electrosteel in steel production. |
