Abstract: The influence of specific surface and packed density on the specific sorption of exfoliated graphite (EG) with different particles and packed densities was investigated by a wicking method, and both diesel oil and A-grade heavy oil were employed as standard sorbates. The experimental result shows that the specific sorption of refined EG particles on diesel oil is not sensitive to the change of specific surface even from 0. 624 to 34. 200 m2/g, compared with the refined EG particles, worm-like EG ones have significantly high specific sorption on diesel oil, and the packed density of EG influences the specific sorption on A-grade heavy oil greatly.
