coke (bituminous) (modified bituminous material, bituminous material, ... Materials (hierarchy name)) |
|
Note: The dark, porous, carbonized residue left after the destructive distillation of bituminous coal, petroleum or coal tar pitch. Coal can be converted to coke by heating it in an airless oven to drive off all volatile components. Coke was once made in large quantities as a byproduct when coal was burnt to produce methane. Coke is useful in metallurgy because it burns hotter than coal; it is used primarily as a fuel or as a reducing agent in the iron and steel industry, primarily in blast furnaces. The process for using coke in smelting was developed in the 17th century. In the 18th and 19th centuries coke aided in the expansion of the cast iron and steel production. Coke can also be converted to graphite.

Additional Notes: |
|
| Dutch ..... Het vaste residu dat overblijft wanneer steenkool zonder luchttoevoer of met beperkte luchttoevoer (carbonisatie) wordt verhit. Cokes worden hoofdzakelijk gebruikt als brandstof of als reduceermiddel in de ijzer- en staalindustrie, hoofdzakelijk in hoogovens. |
| Spanish ..... Residuo sólido que queda cuando se calienta carbón en ausencia de aire o con un suministro limitado (carbonización). Se usa primariamente como combustible o como agente reductor en la industria del hierro y el acero, en particular en los altos hornos. (Oxford Paperback Encyclopedia (1998)) |
