NOVELTY - The method involves adding active carbon on a graphite layer. Supercritical fluid activated carbon is utilized to activate expanded graphite. A plug layer is fully mixed to a single point or multi-point to form sprinkle jet to high temperature and normal pressure in a pyrolysis furnace. The expanded graphite is provided to a multi-phase flow injection process to activate active carbon composite real time to prepare a graphene. Secondary activate active carbon is uniformly scattered in composite material. USE - Method for preparing graphene composite active carbon. ADVANTAGE - The method enables easily manufacturing the graphene composite active carbon.
