1. Chemical analysis of polycyclic aromatic compounds in plastic materials used in indoor environments
University essay from Örebro universitet/Institutionen för naturvetenskap och teknikAbstract : Human bodies are in constant interaction with materials containing known and unknown chemicals of hazardous behavior. One group of chemicals are polycyclic aromatic compounds (PACs) which can be present in both indoor and outdoor materials, commonly in plastics. READ MORE

2. Chelating agents in NiMo sulfided catalysts and the effect of nitrogen compounds on hydrodearomatization and hydrodenitrogenation reactions
University essay from KTH/KemiteknikAbstract : 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. Inhibition Kinetics of Hydrogenation of Phenanthrene
University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)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

4. Development of a Liquid Chromatography Method to Separate and Fractionate EPA’s 16 Priority Polycyclic Aromatic Hydrocarbons (PAHs)
University essay from Örebro universitet/Institutionen för naturvetenskap och teknikAbstract : Polycyclic Aromatic Hydrocarbons (PAHs) are persistent, toxic and carcinogenic environmental pollutants consisting of two or more aromatic rings. The estimation of the toxicity of PAHs can be challenging and time-consuming due to the complexity of PAH-mixtures found in the environment, for example at contaminated sites. READ MORE

5. Multi-energy well kinetic modeling of novel PAH formation pathways in flames
University essay from KTH/Kraft- och värmeteknologiAbstract : Polycyclic Aromatic Hydrocarbons (PAHs) are harmful by-products formed during combustion of hydrocarbons under locally fuel-rich conditions followed by incomplete combustion. PAHs act as precursors during the formation of soot. PAHs and soot are harmful for human health and legislation limits the emission of unburned hydrocarbons and soot. READ MORE
