▎ 摘  要

NOVELTY - Seal coke/sulfonated graphene charcoal material comprises 22-27.5% coal asphalt, 72-77.5% coke material and 0.5-1% additive. The additive is sulfonated graphene or mixture of sulfonated graphene and dispersant. USE - Seal coke/sulfonated graphene charcoal material. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of seal coke/sulfonated graphene charcoal material comprising coating coke material with additive for not less than 5 hours at 80-120 degrees C, drying until no moisture, adding to treated coal asphalt, kneading, rolling, crushing, press molding, calcining and impregnating.
