  2. 1. Cobalt catalyst supports for Fischer-Tropsch synthesis

    Author : Fatima Pardo-Tarifa; Lars J. Pettersson; Olga Guerrero; KTH; []
    Keywords : Silica; alumina; zirconium; cerium; mesoporous materials; nanoparticles; microemulsion; atrane route; cobalt catalyst; Fischer-Tropsch synthesis; Chemical Engineering; Kemiteknik;

    Abstract : In the Fischer-Tropsch (FT) synthesis, CO and H2 (synthesis gas) are converted into hydrocarbons that can be further upgraded to high-quality fuels and chemicals. Different carbon sources such as natural gas, coal and biomass can be used as feed-stocks for the synthesis gas. READ MORE

  4. 2. Fischer-Tropsch Synthesis over Cobalt-based Catalysts for BTL applications

    Author : Matteo Lualdi; Christofer Leygraf; Roy Johnsen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; cobalt; Fischer-Tropsch; syngas; selectivity;

    Abstract : Fischer-Tropsch synthesis is a commercial technology that allows converting synthesis gas, a mixture of CO and H2, into fuels and chemicals. This process could be one of the actors in the reduction of oil dependency of the transportation sector. READ MORE

  5. 3. Development of Catalytic Nanomaterials for Three Industrial Processes

    Author : Stylianos Nassos; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fischer-Tropsch; nanotechnology; selective catalytic oxidation of ammonia; hydrogen production; CO2 capture; microemulsion; nanoparticles; activity; syngas; gasified biomass;

    Abstract : Nanotechnology is a relatively new research topic that attracts increasing interest from scientists and engineers all over the world, due to its novel applications. The use of nanomaterials has extended to a broad range of applications, for example chemical synthesis, catalytic combustion and microporous media synthesis, contributing to achievement of improved or promising results.

  6. 4. System studies of different CO2 mitigation options in the oil refining industry: Post-combustion CO2 capture and biomass gasification

    Author : Daniella Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process integration; post-combustion CO2 capture. CO2 capture and storage CCS ; GHG emissions; oil refining industry; CO2 emissions; Fischer-Tropsch FT ; biomass gasification; energy market scenarios;

    Abstract : To reach the objective endorsed by the EU Council for reducing EU greenhouse gas (GHG) emissions by 80-90% compared to 1990 levels by 2050, extensive cuts are necessary in all sectors. The oil refining sector is a major energy user and thus a major GHG emitter. READ MORE

  7. 5. Fischer-Tropsch synthesis from bio-syngas models over cobalt and cobalt-iron alumina supported catalysts

    Author : Dewi Tristantini; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fe:Co-ratio; Cobalt; Bio-syngas; Fe-Co bimetallic; Fischer-Tropsch Synthesis;

    Abstract : Fischer-Tropsch (FT) synthesis is a process in which synthesis gas (syngas), a mixture of H2 and CO, is converted into long chain hydrocarbons mainly over Co- or Fe-based catalysts. The FT synthesis requires an H2/CO molar ratio (usage ratio) of approximately 2.1 above the catalyst surface. If the inlet syngas H2/CO ratio is less than 2. READ MORE
