| Abstract: | Fast pyrolysis char of larch sawdust was used to prepare activated carbon by steam activation.The optimal activation parameters were obtained as temperature 800 degrees C and activation time 20 min.The activation yield of activated carbon was 51 percent,the adsorption value of methylene blue was 232 mg/g,and iodine adsorption value was 968 mg/g under this condition,which showed an excellent performance in decolorization.Microstructure analysis showed that the fast pyrolysis char was mainly formed by the mic... |
