Novel anode catalysts have been developed for sour natural gas solid oxide fuel cell (SOFC) applications. Sour natural gas comprises light hydrocarbons, and typically also contains H2S. An alternative fuel SOFC that operates directly on sour natural gas would reduce the overall cost of plant...
The objective of this dissertation was to find novel adsorbents addressing problems associated with acid gases. They are the most common contaminants in multiple aspects of petroleum processing and combustion gas clean up, which reduce the efficiency of petroleum refining and product quality....
The ability to detect and quantify presence and concentration of unknown gasses is sought for applications ranging from environmental monitoring to medical analysis. Metal oxide based chemical sensing technology currently exists but the ability to provide a compositional gas breakdown reliably...
This thesis is focused on the studying the role that model sulfur-containing molecules have in corrosion reactions on relevant metallurgies. This was done by using a design of experiments where a number of sulfur-based compounds were reacted with various metallurgies. The 8 model sulfur compounds...
In this research, LSB10T/YSZ composite anode with VOx/TiO2 is used to improve the electrochemical performance, coking resistance and sulfur tolerance of high temperature SOFC fed by 5000 ppm H2S containing methane. The ionic and electronic conductivities of La0.4Sr0.5Ba0.1TiO3 were studied with...
