  1. 1. Hydroconversion of model Fischer‑Tropsch wax over noble metal/silica-alumina catalysts

    Författare :Francesco Regali; Magali Boutonnet; J.W. Niemantsverdriet; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; hydroconversion; Fischer-Tropsch wax; n-hexadecane; bifunctional hydrocracking; hydrogenolysis; silica-alumina; platinum; palladium;

    Sammanfattning : Synthetic fuels produced using the Fischer-Tropsch technology will play an important role in the future of the transportation sector. The Fischer-Tropsch synthesis (FTS) allows converting synthesis gas (CO + H2) into fuels of outstanding quality. The synthesis gas can be obtained from different carbon sources: natural gas, coal and biomass. LÄS MER

  3. 2. Catalytic conversion of biomass-derived synthesis gas to liquid fuels

    Författare :Rodrigo Suárez París; Magali Boutonnet; Agustín Martínez Feliu; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofuels; Fischer-Tropsch wax; higher alcohols; hydroconversion; kinetic modelling; methanol cofeeding; microemulsion; MoS2; noble metal; syngas; Chemical Engineering; Kemiteknik;

    Sammanfattning : Climate change is one of the biggest global threats of the 21st century. Fossil fuels constitute by far the most important energy source for transportation and the different governments are starting to take action to promote the use of cleaner fuels. LÄS MER

  4. 3. Hydrodeoxygenation (HDO) catalysts Characterization, reaction and deactivation studies

    Författare :Houman Ojagh; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Poisoning; Carbon deposition; Ring opening; Hydrodeoxygenation HDO ; Deactivation; Hydroconversion; Brønsted acid sites; Renewable diesel; Sulfided phase;

    Sammanfattning : Production of biomass derived fuels such as renewable diesel, are primarily intended to reduce the reliance of the conventional engines on petroleum fuels as well as the emission of CO2 from fossil hydrocarbons. Hydrodeoxygenation (HDO) is a powerful technique that has been regularly used in the fuel upgrading processes. LÄS MER
