  • Densified carbonaceous bodies
    Patent number: 4894287
    Abstract: A liquid formulation containing furfural, para toluene sulfonic acid and tetraethylene glycol is impregnated into fine grained, isotropic graphite bodies and then polymerized and pyrolyzed. That increases the density of the impregnated body and improves it surface finish.
    Type: Grant
    Filed: February 22, 1985
    Date of Patent: January 16, 1990
    Assignee: Union Oil Company of California
    Inventor: Edward E. Hucke
  • Densified carbonaceous bodies with improved surface finishes
    Patent number: 4761272
    Abstract: A liquid impregnant containing furfural, an acid catalyst and a pore-forming agent comprising a surfactant, e.g. a polyalkylene oxide adduct, is impregnated into fine grained, isotropic graphite bodies and then polymerized and pyrolyzed. An increase in the density of the impregnated body and an improved surface finish is obtained by means of the liquid impregnant and method of this invention.
