    Sammanfattning : Heterogeneous electrocatalysis is the usage of solid materials to decrease the amount of energy needed to produce chemicals using electricity. It is of core importance for modern life, as it enables production of chemicals, such as chlorine gas and sodium chlorate, needed for e.g. materials and pharmaceuticals production. LÄS MER

  2. 2. Novel monogalactoside galectin inhibitor scaffolds : Guiding selectivity with heteroaromatic interactions

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

    Författare :Francesco Regali; Magali Boutonnet; J.W. Niemantsverdriet; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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

  5. 5. Chemo-enzymatic cascades for the synthesis of chiral high-value chemicals

    Författare :Lisa Marx; Per Berglund; Sabine Flitsch; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER;

    Sammanfattning : Chiral amines are frequent in today´s top selling pharmaceuticals. Classical organic synthesis of pharmaceuticals is often work intensive involving many synthesis steps, the use of protection group chemistry, heavy metal catalysts and chiral crystallization techniques. LÄS MER
