  1. 1. Pyrolysis of biomass. Rapid pyrolysis at high temperature. Slow pyrolysis for active carbon preparation

    Author : Rolando Zanzi; KTH; []
    Keywords : rapid pyrolysis; pyrolysis; wood; agricultural residues; biomass; char; tar; gas; char reactivity; gasification; steam; active carbon;

    Abstract : Pyrolysis of biomass consists of heating solid biomass inthe absence of air to produce solid, liquid and gaseous fuels.In the first part of this thesis rapid pyrolysis of wood(birch) and some agricultural residues (olive waste, sugarcanebagasse and wheat straw in untreated and in pelletized form) athigh temperature (800ºC–1000ºC) is studied ina free fall reactor at pilot scale.
