Preparation of activated carbons from lignin by NaOH activation and processing optimization

    Graphical Abstract
    • Abstract
  • Activated carbons（ACs）were prepared from lignin by NaOH activation. The influence of NaOH/lignin ratio, activation temperature and time on Brunauer-Emmett-Teller (BET) surface areas of ACs was investigated. Based on experimental optimization methods including the central composite design and response surface methodology, optimized parameters were found and the maximum BET surface area of ACs was 1437.20m2/g when lignin was activated at 751℃ for 57min with a NaOH/lignin ratio of 2.06.
