1. Deactivation of cobalt and nickel catalysts in Fischer-Tropsch synthesis and methanation
Abstract : A potential route for converting different carbon sources (coal, natural gas and biomass) into synthetic fuels is the transformation of these raw materials into synthesis gas (CO and H2), followed by a catalytic step which converts this gas into the desired fuels. The present thesis has focused on two catalytic steps: Fischer-Tropsch synthesis (FTS) and methanation. READ MORE

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

3. On the Function of Ceria Supported Rhodium Catalysts for Methanation of Carbon Dioxide
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. Methanation of biosyngas in a fluidized bed reactor
Abstract : Rising prices for fossil fuels and concerns over the climate change increase the interest in renewable energies. Synthetic natural gas (SNG) can be an option, filling the request for alternatives in the transportation sector, where the dependence on the oil is very strong. READ MORE

5. Utilizing CO2 from biomethane production : Sustainability and climate performance
Abstract : Biogas solutions offer many benefits for the environment and society, including organic waste treatment as well as being an enabler for energy and nutrient recovery. The products of anaerobic digestion are a biogas, which contains a share of 30 to 50% carbon dioxide (CO2) and 50 to 70% methane, and a liquid remanent, rich in nutrients. READ MORE
