  1. 1. World oil supply and unconventional resources : Bottom-up perspectives on tight oil production

    Författare :Henrik Wachtmeister; Mikael Höök; Roger Bentley; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; oil supply; oil production; unconventional resources; tight oil; shale oil; bottom-up model; projections; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Sammanfattning : Oil is the world’s largest primary energy source. It dominates the transportation sector which underpins the world economy. Yet, oil is a nonrenewable resource, destined not to last forever. In the mid-2000s global conventional oil production stagnated, leading to rising oil prices and fears of permanent oil scarcity.

  3. 2. World oil supply in the 21st century : A bottom-up perspective

    Författare :Henrik Wachtmeister; Mikael Höök; Jamie Speirs; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oil supply; oil production; oil prices; bottom-up; projections; conventional oil; tight oil; shale oil; Natural Resources and Sustainable Development; Naturresurser och hållbar utveckling;

    Sammanfattning : Oil-fuelled progress was a defining feature of the 20th century, and still today, oil remains the world’s largest primary energy source. Yet, oil is a non-renewable and carbon-intensive resource, either depletion or resulting carbon emissions will ultimately limit its use. LÄS MER

  4. 3. Development of ring-opening catalysts for diesel quality improvement

    Författare :Ulf Nylén; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; ring opening; naphthenes; cetane number improvement; indan; light cycle oil LCO ; Pt-Ir catalyst; catalyst characterization; aromatic sulphur compounds; GC-SCD; distribution; analysis;

    Sammanfattning : The global oil refining industry with its present shift inproduct distribution towards fuels such as gasoline and dieselwill most likely hold the fort for many years to come. However,times will change and survival will very much depend onprocessing flexibility and being at the frontiers of refiningtechnology, a technology where catalysts play leading roles. LÄS MER

  5. 4. Ring-opening catalysts for cetane improvement of diesel fuels

    Författare :Ulf Nylén; Magali Boutonnet; Sven Järås; François Garin; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ring opening selective ; naphthenic structure; indan; light cycle oil LCO ; cetane; Pt-Ir catalyst; microemulsion; XPS; TPR; TEM; DRIFTS; sulphur analysis; GC-SCD; Chemical engineering; Kemiteknik;

    Sammanfattning : The global oil refining industry with its present product distribution essentially shifted towards fuels such as gasoline and diesel will most likely hold the fort for considerable time. However, conditions are changing and refinery survival will very much depend on long-term planning, process and product flexibility and being at the frontiers of refining technology, a technology where catalysts play leading roles.

  7. 5. Engineering Lipid Metabolism for Production of Oleochemicals in Saccharomyces cerevisiae

    Författare :Paulo Teixeira; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; oleochemicals; lipid homeostasis; Saccharomyces cerevisiae< i>; lipid metabolism;

    Sammanfattning : Oleochemicals are chemicals usually derived from plant oils or animal fat. Large use of plant oil derivatives as replacements for petroleum-derived chemicals brings sustainability issues from extensive cultivation of oil plants in restricted regions. LÄS MER
