Adsorptive Characteristics and Micropore Structure of ActivatedCarbon Prepared from Different Biomass Materials

摘要

The activated carbons have been prepared from different biomass materials, such as wood scraps, palm seeds, corn cob andstalk, by steam activation at the temperature of 650°C～950°C. The activated carbons prepared from different biomassmaterials exhibit a different pore structure and adsorption properties. The activation temperature in steam has a strong effecton development of microspore structure of activated carbons. A higher activation temperature, such as 850°C～950°C, willbenefit to prepare an activated carbon with the abundant micro and mesopore structure and high adsorptive properties.
