  3. 2. 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

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wood; acetylated wood; surface modification; superamphiphobicity; superhydrophobicity; plastron; silicone nanofilaments; multicycle Wilhelmy plate method.; Trä; acetylerat trä; ytmodifiering; superamfifobicitet; superhydrofob; plastron; silikon-nanofilament; multicykel Wilhelmy-metod; Building Materials; Byggnadsmaterial;

    Sammanfattning : The increasing awareness of sustainability motivates the development of building materials from renewable resources. The requirements of wood-based products with improved durability, for example, an enhanced liquid repellence, is still a challenge. LÄS MER

  5. 4. Nonionic Microemulsions: Dependence on Oil Chain Length of the Surfactant Curvature Elastic Properties

    Författare :Joakim Balogh; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Light Scattering; NMR relaxation NMR self-diffusion; SANS contrast variation and contrast matched studies; saddle play modulus; made by C12E5; Nonionic microemulsion; balanced microemulsion; Fysikalisk kemi;

    Sammanfattning : The aim with this thesis has been to increase the knowledge about nonionic microemulsions and how they behave with increasing temperature. I have studied Nonionic Microemulsions made from C12E5, water and oil, with predominally hexadecane as oil, but also with octane, decane, dodecane and tetradecane as oil. LÄS MER

  7. 5. NMR Diffusometry and Dynamic NMR Microscopy Studies of Colloidal Systems

    Författare :Helena Wassenius; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; diffusion behaviour; dynamic NMR microscopy; NMR diffusometry; core-shell latex particles; NMR velocimetry; rheology; colloidal systems;

    Sammanfattning : In this thesis, the NMR diffusometry and dynamic NMR microscopy methods were shown to be useful techniques with a great potential for the study of colloidal systems. In Paper I-II, NMR diffusometry was used to study the behaviour of surfactant and polymer molecules that are normally important components in colloidal dispersions and emulsions. LÄS MER
