Embodiment 1
[0037] The jute stalks are washed, dried, and carbonized by dry distillation, and pulverized to obtain jute stalk particles, 0.126mm≦particle size≦0.55mm.
[0038] Put 120g of jute stalk carbonized particles in a 1000ml ceramic evaporating dish, and place the ceramic evaporating dish containing jute stalk charcoal particles in the middle of the muffle furnace, and use the intelligent temperature controller Controller B180 to control the activation temperature at 800°C. The steam generated by the generator is 200g.h -1 The flow is sent into the muffle furnace, and after 2 hours of activation, the discharge is sealed and cooled.
