  1. 1. Chelating agents in NiMo sulfided catalysts and the effect of nitrogen compounds on hydrodearomatization and hydrodenitrogenation reactions

    University essay from KTH/Kemiteknik

    Author : Lilla Lukovicsová; [2022]
    Keywords : hydrotreating; NiMo Al2O3; HDN; HDA; trickle-bed microreactor; Type I and II hydrotreating catalysts; Hydrering; NiMo Al2O3; HDN; HDA; porlbädd reaktor; Typ I och II hydrering katalysatorer;

    Abstract : Hydrering är en viktig process för att producera produkter med önskade egenskaper samt att uppfylla de lagliga krav som existerar med avseende på miljö och hälsa. Reaktionerna som sker vid hydreringen är katalytiska vilket innebär att förstå sam utnyttja de mest lämpliga katalysatorerna är av yttersta vikt. READ MORE

  3. 2. Conversion of CO2 to higher alcohols

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Joshua Higby; [2020]
    Keywords : CO2 hydrogenation; higher alcohols; modelling; process intensification;

    Abstract : I rapporten framgår det en termodynamisk analys för reverse water gas shift med att sammanmata etanol för att undvika det långsammaste steget i reaktionen för att producera högre alkoholer. Ifrån ett termodynamiskt perspektiv, verkar det möjligt att utgå ifrån reverse water gas shift för att producera högre alkoholer vid 100 bar med en temperatur på 300C . READ MORE

  4. 3. Inhibition Kinetics of Hydrogenation of Phenanthrene

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

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

    Abstract : 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. READ MORE

  5. 4. Computational Modeling and Characterization of the Human Tri-Heteromeric GABAA Receptor

    University essay from KTH/Tillämpad fysik

    Author : Michael Luxemburg; [2019]
    Keywords : ;

    Abstract : -aminobutyric acid receptors of type A (GABAARs) are the majorinhibitory neurotransmitter receptors in the human brain, andare modulated by a vast range of exogenous molecules, such assedatives and anesthetics. In the last year, the first cryo-electronmicroscopy (cryo-EM) images of the closed and desensitized statesof the GABAAR were released, enabling fruitful research throughsimulations of these complex proteins.

  6. 5. Development of a modern catalytic system for the production of C3+ aliphatic alcohols by the Fischer-Tropsch method

    University essay from KTH/Energiteknik

    Author : Aravind Ganesan; [2019]
    Keywords : syngas; Cobalt; Fischer-Tropsch; alcohols; hydrocarbons; syngas; kobolt; Fischer-Tropsch; alkoholer; kolväten;

    Abstract : This thesis deals with converting a mixture of H2 and CO, also referred to as syngas or producer gas, to higher or mixed alcohols and other fuels through a process called Fischer Tropsch Synthesis (FTS). It is a beneficial pathway that minimizes the dependence on oil and similar fossil fuels which contribute to rapid climate change by releasing harmful greenhouse gases. READ MORE
