Term: fluid coke
https://doi.org/10.1351/goldbook.F02449

Definition:
The carbonization product of high-boiling hydrocarbon fractions (heavy residues of petroleum or coal processing) produced by the fluid coking process.

Note: Fluid @C01142@ consists of spherulitic grains with a spherical layer structure and is generally less graphitizable than @D01577@. Therefore, it is not suitable as @F02364@ for @P04731@ products and is also less suitable for polycrystalline carbon products. Because of its isotropy it is less suitable to produce an anisotropic @S06233@. All @C01142@ contain a fraction of matter that can be released as volatiles during heat treatment. This @M03722@, the so-called volatile matter, is in the case of fluid @C01142@ about 6 wt.%.
