Graphite crystals are thought to possess two different types of 'sites', referred to hereinafter as 'oleophilic sites' and 'polar sites'. The oleophilic sites are present on the basal plane area of graphite crystals and the polar sites are present on the edge area of graphite crystals. The oleophilic sites adsorb long chain paraffinic hydrocarbons and the polar sites adsorb polar compounds, the two types of adsorption being essentially independent.
