Good, R J

The experimental systems required for our research have been acquired. Contact angle measurements on unoxidized Upper Freeport coal and fresh Illinois No. 6 coal show small differences in the contact angles of water under decane. Adsorption measurements on Upper Freeport coal with cyclohexanol in decane reveal adsorption behavior similar to that of octanol. This indicates that the adsorption is taking place on the pore surface of the coal and that the pores are probably greater than 2 nm diameter.
