Aspen Physical Property System - Physical Property Models

The densities of graphitic high-temperature carbons (including cokes) range
from 2.2x10 3 to 2.26x10 3 kg/m 3 . Densities of nongraphitic high-temperature
carbons (derived from chars) range from 2.0x10 3 to 2.2x10 3 kg/m 3 . Most of
the data used in developing this correlation were for carbonized coking coals.
Although data on a few chars (carbonized non-coking coals) were included,
none has a hydrogen content less than 2%. The correlation is probably not
accurate for high temperature chars.
