  1. 1. Anaerobic digestion in continuous stirred tank reactors and plug flow reactors: : Comparison study concerning process performance

    University essay from KTH/Kemiteknik

    Author : Zeko Kocak; [2022]
    Keywords : Anaerobic digestion; municipal waste; continuous stirred tank reactor; plug flow reactor; biogas; Anaerob rötning; kommunalt avfall; kontinuerlig omrörd tankreaktor; pluggflödesreaktor; biogas;

    Abstract : Användningen av kommunalt avfall för att producera förnybar energi, huvudsaklig biogas, uppfyller 8 av Sveriges 16 miljökvalitetsmål. Två typer av rötningsprocesser som används är kontinuerligt omrörda tankreaktorer (CSTR) och pluggflödesreaktorer (PFR). READ MORE

  3. 2. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Virginia Tosi; [2021]
    Keywords : Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

    Abstract : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

  4. 3. Development of headspace solid phase microextraction gas chromatography mass spectrometry method for analysis of volatile organic compounds in board samples : Correlation study between chromatographic data and flavor properties

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Author : Thea Zethelius; [2021]
    Keywords : Solid phase microextraction SPME ; method development; volatile organic compounds VOCs ; food contact material FCM ; flavor experience; design of experiment DoE ; multivariate analysis;

    Abstract : The purpose of this thesis work was to develop a headspace solid phase microextraction gas chromatography mass spectrometry (HS-SPME-GC-MS) method to detect volatile organic compounds (VOCs) in board samples and to statistically investigate potential correlation between chromatographic data and flavor data obtained from a trained panel. The developed method would hopefully serve as a complement to the already established routine analyses at Stora Enso and gain an increased understanding of which VOCs in the board influence its flavor properties.

  5. 4. Optimization of bio-methane production process for combined treatment of sewage & municipal solid waste

    University essay from KTH/Energiteknik

    Author : D.W.N Wijesinghe; [2016]
    Keywords : ;

    Abstract : Handling solid waste such as municipal solid waste (MSW) has become a booming problem in highly populated urban areas. Even though it has a high potential of biogas generation in anaerobic digestion, it is not that successful as a single substrate. READ MORE

  6. 5. Alkylresorcinols as a biomarker for whole grain rye and wheat intake in the finnish diabetes prevention trial

    University essay from SLU/Dept. of Food Science

    Author : Elise Nordin; [2015]
    Keywords : T2D; whole grain; rye; wheat; C17 C21; biomarker; alkylresorcinols; gas chromatography- mass spectrometry GC-MS ;

    Abstract : Type 2 diabetes (T2D) is a public health problem of great concern. Globally it is increasing and it generates a huge economic burden to society and problems for the individuals. READ MORE
