A green method for production of activated carbon and combustible gas was introduced. Without any external reagents and gases, the HO and CO produced by the pyrolysis of bamboo shoot shells were used as activators. The prepared activated carbon had good arsenic adsorption properties with the maximum adsorption capacities of 10.9 mg/g for As(III) and 16.0 mg/g for As(V). The gaseous products were mostly CO and H, with higher heating value of 11.7 MJ/Nm. Thermogravimetric experiments were performed in N, HO and CO atmospheres to simulate the self-activation process and investigate the self-activation mechanism. This work will help to improve the competitiveness of self-activation technology and reduce the production cost of activated carbon.
