TITLE OF THE INVENTION SPHERICAL CARBON MATERIAL, SPHERICAL ACTIVATED CARBON AND PROCESS FOR PREPARING THE SAME ABSTRACT OF THE DISCLOSURE Spherical carbon material or a spherical activated carbon is prepared from an admixture of pitch, amorphous carbon and a viscosity-controlling agent by the process comprising the steps of heating and extruding the admixture into strings, cooling and cutting the strings into fragments, introducing the fragments into hot water to obtain spherical particles of the admixture, removing the viscosity-controlling agent from the spherical particles, infusibilizing the spherical particles with an aqueous solution of an oxidant and carbonizing the spherical particles and/or further activating the carbonized spherical carbon particles.
