  1. 1. 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

  2. 2. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method

    Master-uppsats, KTH/Energiteknik

    Författare :Aravind Ganesan; [2019]
    Nyckelord :syngas; Cobalt; Fischer-Tropsch; alcohols; hydrocarbons; syngas; kobolt; Fischer-Tropsch; alkoholer; kolväten;

    Sammanfattning : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. LÄS MER

    Sammanfattning : This report travels through multiple disciplines to seek innovative and sustainable energy solutions for wastewater treatment plants. The first subject is a report about increased global temperatures and an over-exploitation of natural resources that threatens ecosystems worldwide. LÄS MER

  4. 4. Enhancing the production of biomethane : A comparison between GoBiGas process and new process of combining anaerobic digestion and biomass gasification

    Master-uppsats, Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Författare :Daheem Mehmood; [2016]
    Nyckelord :Aspen Plus; Biomethane; Biomass; Cold gas efficiency; GoBiGas process; Gasification; GoBiGas model;

    Sammanfattning : In recent years, there is a rapid growing interest in the use of biomethane for the transport sector. A new method of combining anaerobic digestion and biomass gasification is proposed.The feasibility study shows that more biomethane can be produced; resulting in an increase in the revenue compared to individual biogas plants.
