  1. 1. Waste-to-Energy : A study on Reaction Kinetics of Tropical Wood Sawdust

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Bertrand Asongwe Tita; [2016]
    Keywords : Tropical biomass; Thermo-gravimetric Analysis TGA ; reaction kinetics; pyrolysis;

    Abstract : The reaction kinetics of Iroko and Mahogany were studied using TGA. The pyrolysis process was achieved using six different heating rates of 2,5,8,12,15 and 20˚C. A 15˚C/min heating rate was used for gasification in steam at different temperatures while varying the concentrations of nitrogen and steam in the process. READ MORE

  4. 3. Torrefaction of biomass : a comparative and kinetic study of thermal decomposition for Norway spruce stump, poplar and fuel tree chips

    University essay from SLU/Dept. of Energy and Technology

    Author : Xun Luo; [2011]
    Keywords : torrefaction; biomass; poplar; Fuel Tree Chips FTC ; stump; heating value; grindability; Kinetic study; activation energy; pre-exponential factor; reaction order; Scanning Electric Microscope SEM ;

    Abstract : Stump biomass is energy rich and stump harvesting for use as fuel become more and more interesting in Sweden. Swedish Forest Agency (2009) has estimated that stump harvesting in Sweden would respond to an annual energy supply of 57 TWh/year. However, stump has not been recognized as a bioenergy resource in Sweden. READ MORE
