2. 11. Investigation of Solid Fuel Conversion in a Fluidised Bed Gasifier – Modelling and Experiments

   Author : Louise Lundberg; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; modelling; biomass; char reactivity; gasification; char conversion; fluidised bed;

   Abstract : A substantial proportion of Sweden’s greenhouse gas emissions originates from the transportation sector, and the Swedish government has set the goal that the entire Swedish vehicle fleet will be independent from fossil fuels by 2030. One of the strategies investigated to achieve this goal is biomass gasification, which is a technology that can be used to transform lignocellulosic materials into a raw gas. READ MORE

4. 12. Pyrolysis of biomass in fluidized-beds: in-situ formation of products and their applications for ironmaking

   Author : Pelle Mellin; Weihong Yang; Blasiak Wlodzimierz; Gerrit Brem; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biomass; Pyrolysis; Fluidized bed; CFD; Blast furnace; Teknisk materialvetenskap; Materials Science and Engineering;

   Abstract : The iron and steel industry emitted 8 % of all CO2 emissions in Sweden, 2011. Investigating alternative energy carriers is the purpose of this thesis. By pyrolyzing biomass, an energetic solid, gaseous and liquid (bio oil) fraction is obtained. READ MORE

5. 13. Fire behaviour of selected polymeric materials : Numerical modelling and validation using microscale and bench scale test methods

   Author : Abhishek Bhargava; Avdelningen för Brandteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; DAEM; pyrolysis modelling; Polymer flammability; mass loss rate; Heat release rate HRR ;

   Abstract : The ability to predict fire behaviour of materials is of key interest to building materials industry. Themain reason for it is expensive fire testing and certification costs borne by the manufacturers to bring a finished product to market. READ MORE

6. 14. Fundamental Study of two Selected Tropical Biomasses for Energy : coconut and cashew nut shells

   Author : Alberto Júlio Tsamba; Wlodzimierz Blasiak; A. K. Gupta; KTH; []
   Keywords : Cashew nut shells; coconut shells; biomass; thermogravimetry; pyrolysis; kinetics; combustion; TECHNOLOGY; TEKNIKVETENSKAP;

   Abstract :  Cashew nut and coconut shells are two potential renewable and environmentally friendly energy sources that are commonly found as agro-industrial wastes in tropical countries. Despite this fact, they are not yet widely studied as such. READ MORE

7. 15. Pyrolysis of Biodegradable Waste for Negative Carbon Emissions

   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pyrolysis; Organic fraction of municipal solid waste OFMSW ; Anaerobic digestion; Bioenergy with carbon capture and storage BECCS ; Methane production; 热解，市政污泥，消化物，碳负排放，生物降解垃圾，甲烷，生物能源与碳捕获和储存; pyrolys; slam; rötrester; negative kolemissioner; biologiskt nedbrytbart avfall; metan; BECCS; Teknisk materialvetenskap; Materials Science and Engineering; Chemical Engineering; Kemiteknik; Energy Technology; Energiteknik;

   Abstract : Bioenergy with Carbon Capture and Storage represents a crucial technology that enables an energy production with negative carbon emissions, which is needed to achieve global climate goals. Appropriated management of biodegradable waste, including biodegradable lignocellulosic waste, sewage sludge, organic fraction of municipal solid waste, can make this contribution. READ MORE
