Abstract
This invention provides a method for enhancing the performance of carbon products in elastomers. [Solution] A method for processing particulate carbon comprises combining pyrolysis carbon with water to form a mixture to form an initial slurry having 1 to 35% by weight of solids, and grinding the pyrolysis carbon to form a grinding slurry containing wet-ground regenerated carbon and water; the volume-weighted particle size distribution of the wet-ground regenerated carbon, measured via scanning electron microscopy, satisfies at least one of the following conditions: D50 is 2700 nm or less, and particles having a particle size greater than 5 microns account for 15% or less.
