The extract (E) and residue (R) from Lower Kittanning bituminous coal were oxidized separately at lOO"C, and the caking properties for the mixtures of R + E, R,, + E, R + E,, and R,, + E,, (R,, and E,, represent oxidized R and E) were measured. It was observed that oxidation of the residue and the e

In a study of the enlargement of pores of coals it has been found that treatment of a bituminous coal (PSOC No. 371, from the Pennsylvania State University Coal Section) with a 5:95 O,:N, stream 4 h at 400ยฐC increases the surface area as measured by nitrogen adsorption at 77K by a factor of at least
