  1. 6. SPME Method for Chemical Analysis of Heavy Organic Trace Compounds in Synthesis Gas

    Kandidat-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Constancia Felise Elemia Freire; Simon Edin; Chang Ho Lee; [2020]
    Nyckelord :;

    Sammanfattning : There currently exists no commercialized method for rapid sampling and analysis of trace tar ingas streams. Solid phase microextraction (SPME) with a polydimethylsiloxane (PDMS) solidphase has been previously investigated as a possible candidate due to its solvent-free natureand reusability. LÄS MER

  3. 7. Modelling the Production of Biofuels via Olefins Oligomerisation

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Nima Mirzaei; [2020]
    Nyckelord :Biofuels; Mathematical Modelling; Process Simulation; Oligomerisation; Fischer-Tropsch; Biobränslen; Matematisk Modellering; Process Simulering; Oligomerisering; Fischer-Tropsch;

    Sammanfattning : The technical feasibility of gasoline and diesel range hydrocarbons production through oligomerisation of olefins, starting from biomass with the intermediary steps of gasfication, water-gas shift reaction and syngas-to-olefins synthesis was investigated, through mathematical modelling and simulation on Matlab. The model for the gasifier was based on minimisation of Gibbs free energy and its results showed that higher carbon efficiencies could be achieved at lower pressures and steam inlet, and more inlet energy, by pre-heating the gasifying agents.

  4. 8. The feasibility of producing and utilizing bioenergy in Linga Linga, Mozambique : Potential resources, conversion techniques and applications

    Kandidat-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Mila Ebrahim; Fanny Lilja; [2019]
    Nyckelord :anaerobic digestion; biochar; biomass; bioenergy; biomass combustion; charcoal; gasifier cookstove; sustainable bioenergy;

    Sammanfattning : The aim of the project was to investigate the possibility of producing and utilizing bioenergy from available local resources in the village Linga Linga, Mozambique. Suitable conversion techniques for producing and utilizing bioenergy were identified through a literature study. LÄS MER

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

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

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

    Sammanfattning : 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. LÄS MER

  7. 10. Hydrogen production from automotive waste via integrated plasma gasification and water gas shift.

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Marco Occhinero; [2019]
    Nyckelord :;

    Sammanfattning : The growing amount of landfilled waste could pose a problem in many parts of the world due to the scarcity of landfilling space and environmental threats. In particular, automotive shredder residue (ASR) waste, a by-product of the dismantling of End of Life Vehicles (ELVs), has been proven to represent an issue in particular in the EU, where countries are struggling to compel to the directives that regulate this type of waste.
