NOVELTY - Dispersion of graphene modified phenolic resin comprises mixing graphene solution and first phenolic resin and dispersing to obtain first graphene modified phenolic resin; and mixing with second phenolic resin. USE - Method for dispersing graphene modified phenolic resin (claimed). ADVANTAGE - The graphene modified phenolic resin has high strength. The method avoids volatilization of formaldehyde. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for: (1) preparation of porous graphene comprising processing biomass carbon source in the presence of catalyst to obtain first intermediate product; incubating at 20-40 degrees C under protective gas condition and raising temperature to 300-400 degrees C to obtain second intermediate product; insulating at 800-900 degrees C under protective gas condition to obtain third intermediate product; incubating at 1100-1300 degrees C under protective gas condition to obtain fourth intermediate product; and cooling to 900-1000 degrees C under protective gas condition; and (2) preparation of porous cellulose comprising hydrolyzing biomass resources in acid; and processing and treating with acid, salt or organic solvent. The catalyst comprises manganese chloride salt, ferrous compound, cobalt compound, and/or nickel compound. The biomass resource comprises plants, agricultural, and/or forestry waste.
