NOVELTY - Biomass charcoal fuel has good combustion, carbonized material is obtained by pulverizing carbonization of a southern stalk, mixing with a graphene oxide modified corn stalk powder, and adding to a biomass molding machine for pressing. USE - Biomass charcoal fuel. ADVANTAGE - The biomass charcoal fuel has lower ignition, is easily combustible. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a method for preparing biomass charcoal fuel, which involves: (A) uniformly dispersing graphene oxide in ionic water, a graphene suspension of 3.2% by mass is prepared, and adjusting graphene oxide suspension pH to 10.5; (B) adding sodium dihydrogen phosphate solution having a mass fraction of 10% in volume ratio of 1:10, adding to the graphene oxide suspension obtained above to obtain a graphene oxide-sodium dihydrogen phosphate suspension; (C) adding the corn stover powder to the graphene oxide-dihydrogen phosphate, mixing suspension, heating at 85 degrees C in a water bath; (D) adding 0.1% cross-linking agent of the corn stover powder, stirring at a rate of 2000 revolutions/minute for 2 hours, then filtering, washing with deionized water, drying; and (E) mixing corn stalk powder and graphene oxide-sodium dihydrogen phosphate suspension in mass ratio of 85-90 g:300 mL.
