  2. 12. A study of ethylene production via the 2-oxoglutarate dependent pathway in S. cerevisiae

    Författare :Nina Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ethylene forming enzyme; Ethylene; respiration rate; Saccharomyces cerevisiae; cultivation; production; nitrogen metabolism; 2-oxoglutarate; enzyme engineering; metabolic modeling;

    Sammanfattning : The detrimental effect of the petroleum industry on the environment combined with the threat of peak oil has driven the exploration for alternative strategies to produce traditional petrochemicals. Biotechnological production could be an alternative, using microorganisms to convert renewable feedstocks into desired products. LÄS MER

  3. 13. Production scheduling and shipment planning at oil refineries : optimization based methods

    Författare :Jan A. Persson; Bjørn Nygreen; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : In the oil refinery industry, companies need to have a high utilization of production, storage, and transportation resources to be competitive. This can only be achieved by proper planning The purpose of this thesis is to contribute to the development of optimization models and solution methods that support the scheduling and planning at refinery companies.

  4. 14. Mobile Computing and Project Communication : - mixing oil and water?

    Författare :Alexander Löfgren; Örjan Wikforss; Per Andersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mobile computing; Project communication; Construction; Implementation; Usefulness; Industrial organisation; administration and economics; Industriell organisation; administration och ekonomi;

    Sammanfattning : The use of mobile and wireless Information and Communication Technology (ICT) tools in geographically distributed project organizations appears to be an appropriate application of new technical capabilities in an existing business environment. But to successfully introduce and adopt a suitable mobile ICT-based project communication platform in an existing operational setting involves a complex framework of socio-technical issues that have to be considered.

  5. 15. Study of bio-oil and bio-char production from thermal and catalytic hydrotreatment of simulated pyrolysis oil under mild conditions

    Författare :Elham Nejadmoghadam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Stabilization; soluble solid; alumina-supported catalyst; insoluble solid char; simulated pyrolysis oil; catalytic hydrotreatment;

    Sammanfattning : Pyrolysis oil derived from fast pyrolysis of lignocellulosic biomass is a promising alternative energy source used to produce renewable biofuels. However, the high reactivity of unsaturated oxygenated compounds in pyrolysis oil results in charring and deactivation of the catalyst under severe hydrotreatment conditions. LÄS MER
