Sammanfattning : In order to fully understand the underlying processes of catalysis, it is vital to combine measurements of the catalyst surface, where the reaction occurs, with measurements of the gas concentration close to the catalyst. We have developed a convenient setup, which uses a single laser system to visualise the gas surrounding a working catalyst in situ at realistic operating conditions. LÄS MER
2. Imaging of the Temperature Distribution in a Catalyst Test Chamber using Laser Rayleigh ScatteringKandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen
Sammanfattning : In order to accurately measure the effect on the gas concentration around catalysts in a high pressure environment using laser based techniques such as Laser Induced Florescence (LIF), accurate temperature maps of the test chamber used are required. In order to create such temperature maps Laser Rayleigh Scattering (LRS) is utilized which allows for a non-intrusive probing of temperatures in a two dimensional measurement area. LÄS MER
