  1. 16. Bio-LNG and CO2 liquefaction investment for a biomethane plant with an output of 350 Nm3/h : A techno-economic-environmental analysis

    University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

    Author : Lars-Julian Vernersson; [2022]
    Keywords : Biomethane liquefaction; Carbon dioxide liquefaction; Biogas upgrading; Liquefaction economy; Biomethane life cycle assessment; Biomethane greenhouse gas saving potential; Biomethane emission factor.;

    Abstract : Stricter requirements from the European Union and the German government regarding the utilization of renewable and sustainable fuels for transportation, power, and heat production are currently in effect. This has led to that heavy transportation companies are looking for a more sustainable alternative to liquefied natural gas, such as liquefied biomethane. READ MORE

  3. 17. Nanoscale characterisation of model Ni-Mo catalyst active phases

    University essay from Lunds universitet/Centrum för analys och syntes

    Author : Jonas Elmroth Nordlander; [2022]
    Keywords : Ni-Mo catalysts; Hydrodeoxygenation; TEM; PXRD; Materials chemistry; Chemistry;

    Abstract : An important stepping stone in transitioning from a fossil-fuel based transportation system is the production of bio-fuels such as bio-oils. For bio-oils to be commercially viable, catalytic upgrading via hydrodeoxygenation is required, typically using Ni-Mo oxide or sulfide catalysts. READ MORE

  4. 18. Bio versus Mineral Hydraulic Oil in Forklifts : Life Cycle Assessment with Different Waste Scenarios and a Market Analysis

    University essay from Linköpings universitet/Industriell miljöteknik

    Author : Maja Hägesten Nilsson; Albin Kylbrink; [2022]
    Keywords : ;

    Abstract : Hydraulic oils are today most often based on mineral oil and thus eventuate in environmental and climate impacts during all its life cycle phases, but there are bio-based alternatives. Hy- draulic oils are widely used in forklifts, and the use of forklifts is increasing due to logistics within e-commerce. READ MORE

  5. 19. Genetically modified tobacco (Nicotiana tabacum) plants for an increased production of wax esters

    University essay from SLU/Dept. Of Plant Biology

    Author : Linn Nilsson; [2022]
    Keywords : Wax esters; metabolic engineering; nicotiana tabacum; fatty acid reductase; phytyl ester synthase;

    Abstract : Wax esters (WE) are naturally occurring lipids consisting of a fatty acid bound to a fatty alcohol with an ester bond. As an alternative to petrochemicals, plant-derived WE:s are of considerable commercial interest as lubricants, but have in recent years also received great attention for their potential as a starting material for bio-fuel production.

  6. 20. Assessment of promoter regulation in Pseudomonas putida using GFP and flow cytometry

    University essay from Lunds universitet/Teknisk mikrobiologi

    Author : Luka Cululejevic; [2022]
    Keywords : applied microbiology; Pseudomonas putida; promoter characterization; aromatic compounds; vanillin; guaiacol; Biology and Life Sciences;

    Abstract : Lignin is found in all biomass and is an abundant natural source of aromatic compounds. It has the potential to serve as a renewable raw material for a variety of chemicals currently derived from fossil fuel sources such as muconic acid, an important platform chemical. Kraft lignin is a waste stream from the pulp and paper industry. READ MORE
