    Sammanfattning : In the beginning of 2005, the ministry of natural resources in the Kurdistan region of Iraq dividedits territory into more than 50 oil blocks based on geological setting. These oil blocks were awardedlater to different international oil companies for oil investments based on Production SharingContracts (PSCs). LÄS MER

  3. 7. Production of Hydrogen for Oil Refining by Thermal Gasification of Biomass: Process Design, Integration and Evaluation

    Författare :Jean-Florian Brau; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hydrogen; Modeling; Refining; Biomass Gasification; Energy Systems; Process Integration;

    Sammanfattning : Hydrogen is an important part of crude oil refining operations since it is required in several units for the desulphurization and upgrading of various oil fractions. At present, most of the refineries meet their hydrogen demand through methane steam reforming, a refinery unit that can represent up to 25% of the plant’s fossil CO2 emissions. LÄS MER

  4. 8. An evaluation of biodiesel policies : The case of palm oil agro-industry in Indonesia

    Författare :Fumi Harahap; Semida Silveira; Serina Ahlgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; palm oil; biodiesel; Indonesia; policy evaluation; policy coherence analysis; land allocation; sectoral policy goals; life cycle cost analysis; biodiesel cost competitiveness; biorefinery; Energy Technology; Energiteknik;

    Sammanfattning : Oil palm has flourished as an economically vital crop in Indonesia given its use in both food and non-food products (including biodiesel) for domestic and export markets. However, the expansion of oil palm plantations in Indonesia is controversial. LÄS MER

  5. 9. Generation of synthesis gas for fuels and chemicals production

    Författare :Per Tunå; Avdelningen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synthetic fuels and chemicals; gasification; gas conditioning; simulation; tar-cracking;

    Sammanfattning : Many scientists believe that the oil production will peak in the near future, if the peak has not already occurred. Peak oil theories and uncertain future oil deliveries have stimulated interest in alternative sources of fuel and chemicals. LÄS MER

  7. 10. Application of Synthetic Biology for Biopolymer Production using Saccharomyces cerevisiae

    Författare :Alejandro Muñoz De Las Heras; Teknisk mikrobiologi; []
    Nyckelord :Saccharomyce cerevisiae; Xylose; Poly-3-d-hydroxybutyrate PHB ; NADH; NADPH; Acetyl-CoA; Metabolic engineering;

    Sammanfattning : Plastics are versatile, cheap and durable materials that are omnipresent in modern society. Since most of them are derived from crude oil and are not biodegradable, their production leads to the depletion of fossil fuels and the accumulation of enormous amounts of plastic waste that pollutes ecosystems worldwide.
