1. 11. Biochar in the Höganäs sponge iron process – techno-economic analysis of integrated production

   University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

   Author : Oscar Olofsson; [2018]
   Keywords : Techno-economic analysis; system modeling; system integration; biochar; biomass; pyrolysis; sponge iron;

   Abstract : Biomass-based reducing agents have a potential to substitute fossil reducing agents in the steel industry. However, the industrial use of biomass-based reducing agents is currently in an early stage of development and has not yet been considered as a means to reduce fossil CO2 emissions, even though the use of fossil-based reducing agents for the iron and steel making cause the highest share of CO2 emissions.

3. 12. Modelling of Biomass Pyrolysis with Ex-situ Catalytic Upgrading for Bio-crude Production

   University essay from KTH/Materialvetenskap

   Author : Febryana Nugrahany; [2018]
   Keywords : ex-situ catalytic upgrading; slow pyrolysis; screw reactor; fixed bed catalytic reactor; process design;

   Abstract : This study presents a techno-economic assessment of slow pyrolysis of pine sawdust continued by ex-situ catalytic upgrading. The overall process consists of six sections: feed drying, pyrolysis, vapor filtration, ex-situ catalytic upgrading, vapor quenching, and combustion of permanent gas. READ MORE

   University essay from KTH/Energiteknik

   Author : Ioannis Asvestas; [2018]
   Keywords : ;

   Abstract : The society is striving to tackle the over-extraction of Earth´s resources due to the ongoing population rise. The increased needs of energy and material resources leads to a growing volume of materials waste, which include a variety of dangerous pollutants among them. READ MORE

5. 14. Biochar: a win-win-win solution for sustainable small-scale farming in Sweden?

   University essay from Lunds universitet/Miljövetenskaplig utbildning

   Author : Malin Stensson; [2018]
   Keywords : Biochar; carbon; climate change; agriculture; resilience; yield; energy production; sustainable farming; sustainable agriculture; pyrolysis; syngas; bio-oil; Agriculture and Food Sciences; Earth and Environmental Sciences;

   Abstract : Biochar is a recalcitrant carbon rich solid product widely praised for the ability to improve soil fertility and sequester carbon, thereby improving crop yields and mitigating climate change. In addition to this, gaseous by products from production can be combusted for energy. READ MORE

6. 15. Coke characterization on HZSM-5, Fe/ZSM-5, Ni/ZSM-5, and Fe-Ni/ZSM-5 from Catalytic Fast Pyrolysis of Biomass

   Abstract : The combustion of fossil fuels has for a long time been a problem from an environmental and sustainability point of view, especially when it comes to the emissions of atmospheric carbon dioxide. The environmental concern has for instance shifted the attention towards finding new sustainable alternatives for producing chemicals and fuels, as a substitute to today’s dependence on fossil based crude oil.
