  1. 1. Assessment of the energetic feasibility of a novel CHP biorefinery concept

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Ângelo Miguel Mendes Ferreira; [2023]
    Nyckelord :biorefinery; bioenergy; biomimicry; combined heat and power; Earth Power Lodge; Technology and Engineering;

    Sammanfattning : This study investigates the potential for energetic self-reliance in an integrated biore- finery, the Earth Power Lodge (EPL), which aims to convert waste into valuable by- products through bio- and thermochemical conversion processes. The primary questions addressed include assessing the necessity of external propane to sustain the pyrolysis process and the net energy output of the ThermoChemical Reactor (TCR) process when fractional distillation is applied to the resulting bio-oils.

  3. 2. Classification of a Sensor Signal Attained By Exposure to a Complex Gas Mixture

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Rabnawaz Jan Sher; [2021]
    Nyckelord :Classification; Random Forest; Linear Discriminant Analysis; Naive Bayes; Principal Component Analysis; Drift; Baseline Compensation; Normalization; Sensor; Signal Preprocessing.;

    Sammanfattning : This thesis is carried out in collaboration with a private company, DANSiC AB This study is an extension of a research work started by DANSiC AB in 2019 to classify a source. This study is about classifying a source into two classes with the sensitivity of one source higher than the other as one source has greater importance. LÄS MER

  4. 3. Development of an analytical method for the screening of meaty flavors in commercial foodstuff by SPME-GC/O-MS

    Master-uppsats, Lunds universitet/Livsmedelsteknik och nutrition (master)

    Författare :Ioannis Protopappas; [2021]
    Nyckelord :Gass Chromatography; Mass spectrometry; Meaty flavors; Aromas; Solid pahse microextraction; Mallaird; Lipid degradation; Food technology; Agriculture and Food Sciences;

    Sammanfattning : The aim of the project was to develop a methodology for the chromatographic analysis able to identify the key odorants in meaty food products. The approach was based on the analysis of an already in market product and the theoretical background of the meaty flavors sensorially. LÄS MER

  5. 4. Development of a GC Method for the Quantification of Short Chain Carboxylic Acids in Aqueous Solution

    Kandidat-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Anton Åkervall; [2020]
    Nyckelord :DAI-GC-FID; Direct Aqueous Injection; Gas Chromatography; Flame Ionization Detector; SCFA; Short Chain Fatty Acids; Formic Acid; Acetic Acid; Lactic Acid; EGR; Exhaust Gas Recirculation; CAC; Charged Air Cooler; FFD; Fractional Factorial Design;

    Sammanfattning : Petroleum powered vehicles emit volatile organic compounds (VOCs) through combustion that contributes to the pollution of the environment. A technique in the 1970s was developed to decrease these emissions, especially for nitrogen oxides (NOx) and sulphuric oxides (SOx) which is called exhaust gas recirculation (EGR). LÄS MER

  7. 5. Application of some modern analytical techniques for investigations of non-metallic inclusions in steel samples

    Master-uppsats, KTH/Materialvetenskap

    Författare :Wan Zhiyue; [2018]
    Nyckelord :Non-metallic Inclusions; Electrolytic Extraction; Fractional Gas Analysis; Zirconium Addition; Calcium Treatment;

    Sammanfattning : The non-metallic inclusions (NMI) have large influence on steel properties. Therefore, evaluation of inclusion size, number, composition and morphology by using modern analytical techniques are very important for control of steel production and steel quality. Three dimensional analysis method of electrolytic extraction is applied in this work. LÄS MER
