  5. 4. Characterization of activated carbon produced from coffee residues by chemical and physical activation

    Master-uppsats, KTH/Skolan för kemivetenskap (CHE)

    Författare :Javier Sanchez; [2011]
    Nyckelord :activated carbon; coffee residues; chemical acivation; physical activation; surface characteristics;

    Sammanfattning : Activated carbons are one of the most used adsorbents with lots of applications in many sectors. Activated carbons can be produced from lignocellulosic materials with a large content of carbon. Coffee is the second trade most consumed all over the world; hence their residues can be treated in order to give a value. LÄS MER
