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

    Master-uppsats, KTH/Kemiteknik

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

    Sammanfattning : 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). LÄS MER

  3. 2. Modelling the Production of Biofuels via Olefins Oligomerisation

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Nima Mirzaei; [2020]
    Nyckelord :Biofuels; Mathematical Modelling; Process Simulation; Oligomerisation; Fischer-Tropsch; Biobränslen; Matematisk Modellering; Process Simulering; Oligomerisering; Fischer-Tropsch;

    Sammanfattning : The technical feasibility of gasoline and diesel range hydrocarbons production through oligomerisation of olefins, starting from biomass with the intermediary steps of gasfication, water-gas shift reaction and syngas-to-olefins synthesis was investigated, through mathematical modelling and simulation on Matlab. The model for the gasifier was based on minimisation of Gibbs free energy and its results showed that higher carbon efficiencies could be achieved at lower pressures and steam inlet, and more inlet energy, by pre-heating the gasifying agents.

  4. 3. Inhibition Kinetics of Hydrogenation of Phenanthrene

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Johannes Johansson; [2019]
    Nyckelord :Catalytic hydrotreating; Phenanthrene; Inhibition kinetics; Model development; Nonlinear regression;

    Sammanfattning : In this thesis work the hydrogenation kinetics of phenanthrene inhibited by the basic nitrogen compound acridine and the non-basic carbazole was investigated. Based on a transient reactor model a steady state plug flow model was developed and kinetic parameters were estimated through nonlinear regression to experimental data. LÄS MER

  5. 4. Concentrated Solar Thermal Plant for Future Fuels Production : Process Modeling and Techno-economic Analysis of Syngasoline, Syndiesel, Ethanol and Methanol Production Using Thermochemical Cycle based on Metal Oxide

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Philipe Gunawan Gan; [2018]
    Nyckelord :;

    Sammanfattning : Concentrated Solar Thermal technology (CST) is a very promising renewable energy technology and has a broad range of use. Conventionally, CST systems are mostly used for power generation according to the Rankine cycle and thus often referred to as Concentrated Solar Power (CSP). LÄS MER

  7. 5. Optimal steady-state design of bioreactors in series with Monod growth kinetics

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Avdelningen för systemteknik

    Författare :Molin Hanna; [2018]
    Nyckelord :bioreactor; CSTR; PFR; optimization; modelling; Monod kinetics; decay rate; bioreaktorer; CSTR; PFR; optimering; modellering; Monod-kinetik; avdödningshastighet;

    Sammanfattning : Bioreactors are used to carry out bioprocesses and are commonly used in e.g. biogas production and wastewater treatment. Two common hydraulic models of bioreactors are the continuous stirred tank reactor (CSTR) and the plug-flow reactor (PFR). LÄS MER
