  1. 1. Reforming of a Tar Model Compound Using Iron Catalysts

    University essay from KTH/Processteknologi

    Author : Celia Pérez Guijarro; [2022]
    Keywords : Biomass gasification; synthesis gas; tar; iron catalyst; reforming; Biomassaförgasning; syntesgas; tjära; järnkatalysator; reformering;

    Abstract : Den internationella medvetenheten om hotet med växthusgaser har bidragit till en prioriterad utveckling av alternativa och rena tekniker baserade på förnybara i stället för fossila bränslen. Biomassaförgasning är en teknik för framställning av icke-fossil energigas från biomassa. READ MORE

  3. 2. Investigation of a CO-Production of Substitute Natural Gas and Biomethanol Plant Compared to Stand Alone Biomethanol Plant

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Susanne Brixland; [2019]
    Keywords : biomethanol; SNG; substitute natural gas; co-production; gasification; gasifier; biomass; syngas; chemical engineering; kemiteknik; Chemistry; Technology and Engineering;

    Abstract : Climate change is one of humanities greatest challenges; the greenhouse gases in the atmosphere are still increasing. There is not one solution that will fix this problem several different products, raw material and technologies are required to take the steps towards a renewable society. READ MORE

  4. 3. Characterization of biomass pyrolysis and gasification using Raman Spectroscopy

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Author : Henrik Johansson; [2018]
    Keywords : Raman; Raman Spectroscopy; Raman scattering; biomass; biofuel; thermal conversion; pyrolysis; gasification; laser diagnostics; laser-induced fluorescence; LIF; energy; wood pellets; ammonia; aldehydes; ketones; formaldehyde; acetaldehyde; acetone; combustion physics; Physics and Astronomy;

    Abstract : This thesis examines the emissions formed during pyrolysis and gasification of lignocellulosic biomass in pellet form, using vibrational Raman spectroscopy. Seven different samples are studied during the pyrolysis process and six of these are also studied during gasification. READ MORE

  5. 4. Potential of chemical recyclingto improve the recycling of plastic waste

    University essay from KTH/Energi och klimatstudier, ECS

    Author : Martyna Solis; [2018]
    Keywords : recycling; chemical recycling; plastic waste; plastic packaging; recycling rates; circular economy; Sweden; Stockholm; Stockholm Exergi; återvinning; kemisk återvinning; plastavfall; plastförpackning; återvinningsgrad; cirkulär ekonomi; Sverige; Stockholm; Stockholm Exergi;

    Abstract : Chemical recycling can improve the plastic recycling rates and reduce the level of CO2 from fossil plasticsproduction. Thus, it is seen as an attractive technology in the action towards meeting the emission, circulareconomy and recycling targets. In the Swedish context, it could help reach the carbon neutrality goal by2045. READ MORE

  6. 5. Thermogravimetric analysis and modeling of pyrolysis of macroscopic wood particles

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : YOSRA PERSNIA; [2016]
    Keywords : Biomass; gasification; renewable energy; thermogravimetric analysis; mathematical modeling;

    Abstract : The knowledge of kinetics of pyrolysis is important. It is also challenging to find parameters for kinetic which can be applied at different sizes of biomass. Many researchers have been investigating the pyrolysis behavior of wood powders due to heat and mass transfer limitations. READ MORE
