SPHERICAL ACTIVE CARBON AND PROCESS FOR PRODUCING THE SAME |
摘要 |
An active carbon produced from an infusible carbonaceous material as a raw material, which active carbon when used for prevention of automobile fuel evaporation, etc., would not cause any trouble attributed to dust generation, exhibiting reduced pressure loss; and a process for producing the same. There is provided a spherical active carbon produced from an infusible solid carbon material as a raw material, wherein providing that x represents an average particle diameter (mm) and y an MS hardness (%), when x is in the range of 0.5 to 20, y is >= 100x(1-0.8x1.45<(0.3-x)>). This spherical active carbon can be produced by a process comprising mixing a carbon material with a carbonizable binder; extruding the mixture into a strand form; carrying out rolling granulation so as to obtain a spherical form; rendering the same infusible under appropriate conditions corresponding to the particle size; and performing carbonization and thereafter activation under conditions appropriately restricting the contact with activation gas.
