Abstract
The true density of petroleum coke is a factor of its structure
and properties. As the removal of volatile matter and sulphur from the coke is
accompanied by significant changes in its structure and microporosity,
changes in its density are to be expected. In this paper, the effects of the
removal of volatile matter and sulphur on the true density of petroleum coke
were investigated. The density was found to increase significantly with the
evaporation of the volatile matter as a result of the thermal treatment of
the coke at a temperature of 1200 K. Removal of part of the sulphur in the
coke led also to a significant increase in the value of its true density.
Temperatures greater than 1600 K were necessary for effective sulphur
removal
