2. 1. On the Function of Ceria Supported Rhodium Catalysts for Methanation of Carbon Dioxide

   Author : Felix Hemmingsson; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HE-XRD; Catalytic methanation; AP-XPS; In situ spectroscopy; DRIFTS; Sabatier reaction; CO2 reduction; Hydrogenation;

   Abstract : Technologies for energy harvesting of sustainable sources such as solar and wind lack an inherent energy buffer. As such, storing excess energy in chemical bonds, for example that of hydrogen (H2), is a desirable complementary concept. READ MORE

4. 2. Transient In Situ Studies on Supported Catalysts: CO2 Methanation and Methane Oxidation

   Author : Felix Hemmingsson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; CH4 oxidation; Catalytic methanation; Hydrogenation; Sabatier reaction; CO2 reduction; HE-XRD; XAS; DRIFTS; AP-XPS; Heterogeneous catalysis; In situ spectroscopy;

   Abstract : This dissertation aims to increase the understanding of important steps in the catalytic CO2 hydrogenation and total methane oxidation reactions over supported noble metal catalysts. A general theme is the role of the metal oxide support for the catalytic reactions. READ MORE

5. 3. Low temperature olivine alteration ; an experimental approach

   Author : Anna Neubeck; Nils Holm; Gretchen Früh-Green; Stockholms universitet; []
   Keywords : Olivine alteration; hydrogen; methane; serpentinization; geokemi; Geochemistry;

   Abstract : Water reacting with minerals to alter or dissolve them is a common phenomenon on Earth, leading to a unique chemical composition of the oceans and continents. The continuous circulation of elements and the chemical reactions between them creates the extraordinary environment prevailing on our Earth today and was probably an important requirement for the onset of life on our planet.

   Abstract : A considerable number of studies indicate that biofuels produced from lignocellulosic biomass will most probably play a significant role in achieving the climate goals stated in the Paris agreement. Several candidate technologies could be implemented to produce these fuels, and one of the most promising is thermal gasification. READ MORE
