AI Technical Summary
Technical Problem
Existing biomass pyrolysis equipment requires an external heat source, resulting in poor production continuity, unstable operation, poor sealing, safety hazards, and environmental pollution.
Method used
The biomass self-heating activated biochar preparation device uses CO2 and H2O generated by pyrolysis as gaseous activators. Activated biochar is prepared through a screw feeder and conveyor belt, and the pyrolysis gas is recycled to avoid external heat source supply.
Benefits of technology
This technology enables the preparation of activated carbon without an external heat source, improving production continuity and equipment stability, reducing energy consumption and environmental pollution, and enhancing the activity and pore structure of biochar.
