    Sammanfattning : How did fossil-fuelled technology find its way to Egypt on its way to global dominance? This thesis presents a socioecological history of energy technologies in agrarian production in pre-colonial Egypt (1820s – 76). It situates them in the nineteenth century, understood as the beginning of the epoch of the Capitalocene; and in Egypt’s case, this is simultaneously part of the rise of Britain’s fossil empire.

  3. 27. ɸ‑sensitivity : A step forward in future fuels evaluation

    Författare :Nika Alemahdi; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Equivalence ratio; ɸ‑sensitivity; Cooperative Fuel Research engine; Method development; Biofuels.;

    Sammanfattning : Internal combustion engine is a developed and established technology whichcontributes largely to the transportation of goods and people. In one hand, theburning of fossil fuels is the main reason for the combustion engines to beconsidered unsustainable while on the other hand, the combustion behaviour ofrenewable fuels is not fully understood yet.

  4. 28. Pretreatment of cellulosic waste and high rate biogas production

    Författare :Solmaz Aslanzadeh; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biogas; Two-stage anaerobic digestion; N-methylmorpholine N-oxide NMMO pretreatment; Lignocelluloses; Textile waste; Biofuels; Resursåtervinning; Resource Recovery;

    Sammanfattning : The application of anaerobic digestion technology is growing worldwide, mainly because of its environmental benefits. Nevertheless, anaerobic degradation is a rather slow and sensitive process. One of the reasons is the recalcitrance nature of certain fractions of the substrate (e.g. LÄS MER

  7. 30. Opportunities to broaden biomass feedstocks in thermochemical conversion technologies

    Författare :Lara Carvalho; Joakim Lundgren; Elisabeth Wetterlund; Erik Furusjö; Andrea Ramírez Ramírez; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Non-woody biomass; Combustion; Gasification; Biofuels; Techno-economic analysis; Energiteknik; Energy Engineering;

    Sammanfattning : Global environmental concerns are motivating a growing interest in broadening the biomass feedstock base in several energy sectors, including (i) the domestic heating sector, presently dominated by stem wood combustion, and (ii) biofuel production, presently dominated by edible crops. The objective of this thesis is to investigate new opportunities to broaden the biomass feedstock in thermochemical conversion technologies. LÄS MER
