  1. 1. Partial methane oxidation from electronic structure calculations

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Adam Arvidsson; [2017]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; ZSM-5 zeolite; density functional theory; microkinetic modelling; Mo6S8 cluster; partial methane oxidation;

    Abstract : Investigating catalytic reactions with computational methods is a powerful approach to understand fundamental aspects of catalytic reactions and find ways to guide catalytic design. Partial methane oxidation is one example of a reaction with intriguing challenges, where a detailed atomistic approach may help to unravel the bottlenecks of this, as of yet, inefficient reaction.

    Abstract : Popular Abstract in Swedish En spännande utmaning för forskare inom både akademin och industrin är att utveckla industriella processer som mer effektivt använder både befintliga som alternativa råvaror för produktion av viktiga kemiska intermediat. Sådana intermediat används i sin tur som råvara för att framställa funktionella och idag ovärderliga material såsom plaster, fibrer, gummin, färger, ytbehandlingsmedel m. READ MORE

  3. 3. Partial methane oxidation: insights from first principles and micro-kinetics calculations

    University dissertation from ; Chalmers tekniska högskola; Gothenburg

    Author : Adam Arvidsson; [2019]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zeolite acidity; zeolites; density functional theory; microkinetic modelling; molybdenum sulfide cluster; partial methane oxidation;

    Abstract : Partial methane oxidation is a much-desired reaction with some intriguing challenges. Not only is there a need to activate methane and oxygen, but there is also a need to control the selectivity and prevent over-oxidation to thermodynamically more stable products, like carbon dioxide and water.

    Abstract : With the progress of high alloy steelmaking processes, it is essential to minimize the loss of valuable metals, like chromium and vanadium during the decarburization process, from both economic as well as environmental view points. One unique technique to realize this aim, used in the present work, is the decarburization of high alloy steel grades using oxygen with CO2 in order to reduce the partial pressure of oxygen.
