Abstract
Disclosed is a process for producing graphene from solid hydrocarbons including biomass and coal. The disclosed method does not require the presence of hydrogen and does not operate under a vacuum. The method begins by converting biomass to a graphene precursor while coal is used as is. Subsequently, the method grinds the graphene precursor to provide a desired particle size. The particles of graphene precursor (biocoal or coal) are converted to graphene by catalytic conversion on metallic foil under atmospheric conditions and in the absence of hydrogen.
