2. 1. Pyrolysis profiles and global kinetics of tropical biomass : coconut and cashew nut shells

   Author : Alberto Júlio Tsamba; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermogravimetry; cashew nut cocnut shells; pyrolysis; kinetics; Other materials science; Övrig teknisk materialvetenskap;

   Abstract : Biomass has been recognised as renewable and environmentally friendly source of energy since decades. Tropical biomasses which are available in large quantities as residues in Latin America, Africa and Asia, have high energy potential for exploitation through thermochemical conversion process, as pyrolysis, gasification or combustion.

4. 2. Formation and Decomposition of Platinum–Thallium Bond, Kinetics and Mechanism. Structural Characterization of Some Metal Cyanides in the Solid State

   Author : Péter Nagy; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; metal–metal bond; platinum; thallium; kinetics; mechanism; stopped flow; oxidative addition; cyano complexes; edta; redox reaction; metal cyanides; X–ray diffraction; Raman; NMR; mercury; palladium; nickel; one dimensional wire;

   Abstract : The kinetic and mechanistic features of a new series ofplatinum-thallium cyano compounds containing a direct andunsupported by ligands metal-metal bond have been studied insolution, using standard mix–and–measurespectrophotometric technique and stopped–flow method.These reactions are interpreted as oxidative addition of the cspecies to the square planar Pt(CN)42-complex.

5. 3. Development of Techniques to Produce Nickel Coated Composite Materials as well as Hollow Nickel Fibres and Kinetic Study of the Process Involved

   Author : Fan Li; Sichen Du; Ioannis Arvanitidis; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nickel; Chemical plating; Kinetics; Model; Hollow nickel fibres; Thermal decomposition; Materials science; Teknisk materialvetenskap;

   Abstract : The present thesis was mainly to study the preparation of nickel composite materials by chemical plating process. Nickel coated boron nitride particles, nickel coated spherical silica particles and nickel viscose composite fibres were prepared. Both experiment and model development were carried out to study the kinetics of the processes. READ MORE

6. 4. Modelling phase separation in Fe-Cr alloys : A continuum approach

   Author : Thomas Barkar; John Ågren; Nele Moelans; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Phase separation; spinodal decomposition; nucleation; diffusion; thermodynamics; kinetics; steel; ferritic;

   Abstract : The formation of Cr-rich and Fe-rich domains upon ageing of an initially homogeneous Fe-Cr alloy at elevated temperatures (300-600 ºC) is commonly referred to as phase separation. The behaviour originates from a miscibility gap in the Fe-Cr phase diagram. READ MORE

7. 5. Isoconversional analysis for the prediction of mass-loss rates during pyrolysis of biomass

   Author : Lina Norberg Samuelsson; Matthaus Babler; Rosana Moriana; Henrik Wiinikka; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pyrolysis; biomass; kinetics; cellulose; spruce; black-liquor; model-free; isoconversional; prediction; pyrolys; biomassa; kinetik; cellulosa; gran; svartlut; model-free; isoconversional; förutsägelse; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

   Abstract : Biomass is the only renewable carbon source that can compete with fossil energy sources in terms of production of materials, chemicals and fuels. Biomass can be transformed into charcoal, liquid and gas through pyrolysis, i.e. pure thermal decomposition. READ MORE
