โœฆ Synopsis

The sorption behavior of four heavy oils with different viscosities into exfoliated graphites with different bulk densities was studied. The maximum sorption capacity ofexfoliated graphite at 25 ยฐC was found to be very high--83 g of grade A heavy oil per 1 g of exfoliated graphite with a bulk density of 0.006 g/cm 3, and also its sorption occurs very rapidly --within 1 min. Sorption capacity depended strongly on bulk density and pore volume of exfoliated graphite, and the time to reach maximum sorption as well as sorption capacity for an exfoliated graphite also depended on the grade of heavy oil used. The present work showed that exfoliated graphite with low bulk density is a promising material for the sorption of heavy oils.

As a preliminary trial for a practical application to recover heavy oil, exfoliated graphite was packed into a plastic bag and its sorption behavior was studied. In order to achieve an extremely high sorption capacity ofexfoliated graphite, special attention had to be paid to the process of picking
