ABSTRACT: Carbonaceous microspheres were prepared from pitch and phenolic resin by suspension. The pitch spheres were made by heating THF solution of pitch at about 150 in glycerin with presence of PVA. The yield of pitch spheres to glycerin was about 5 %. The results showed that the size of pitch spheres had a close relationship with the concentration of pitch and PVA. Resin spheres were made by heating alcohol solution of resol in water with PVA as the surfactant at 120 , by which 70 g resin spheres could be obtained in the 500 mL reactor. The SEM microscopy and the relationship between the average size and preparation conditions were analyzed.
KEY WORDS: Suspension ; Pitch ; Resin ; Carbon microbeads
