  1. 11. Catalytic Upgrading of Fast Pyrolysis Bio-oil Using Zeolites

    University essay from KTH/Kraft- och värmeteknologi

    Author : Elena Wikberg; [2019]
    Keywords : ;

    Abstract : Fast pyrolysis bio-oil is considered as a possible source for production of liquid bio-fuels and bio-chemicals enabling the necessary transition to a renewable energy system. In this Master’s thesis work the upgrading of fast pyrolysis bio-oils with Fluid Catalytic Cracking (FCC) conversion process at industrially relevant conditions is studied using Fluid Catalytic Cracking Micro Activity Test (FCC MAT) unit at RISE ETC in Piteå, Sweden.

    Abstract : The energy consumption in the world is increasing at the same time as the fossil fuel resources are limited. This is causing a rising interest in renewable energy sources over the world. To reduce dependency on fossil fuel sources biomass is an excellent alternative. READ MORE

  5. 14. 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.

  6. 15. 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
