NOVELTY - Preparing high-performance foamed carbon involves adding functionalized graphene to purified fluid catalytic cracking slurry to obtain graphene-modified fluid catalytic cracking slurry. The graphene-modified fluid catalytic cracking slurry is heated and modified to obtain a precursor. The precursor is subjected to self-foaming pyrolysis under high temperature and high pressure to obtain graphene/foam carbon raw material. The graphene/foam carbon raw material is carbonized and graphitized to obtain a graphene-reinforced high-performance foamed carbon. USE - Method for preparing high-performance foamed carbon. ADVANTAGE - The method increases the thermal conductivity to 5-20% and the compressive strength to 10-30%.
