product of high-boiling hydrocarbon fractions (heavy residues of petroleum or coal
processing) produced by the fluid coking
consists of spherulitic grains with a spherical layer structure and is generally
less graphitizable than delayed coke
. Therefore, it is not suitable as filler coke
for polygranular graphite
products and is also less suitable for polycrystalline carbon products. Because of
its isotropy it is less suitable to produce an anisotropic synthetic graphite
. All cokes
contain a fraction of matter that can be released as volatiles during heat treatment.
This mass fraction
, the so-called volatile matter, is in the case of fluid coke
about 6 wt.%.
