title: High-throughput technology for novel SO2oxidation catalysts.
abstract: We review the state of the art and explain the need for better SO2oxidation catalysts for the production of sulfuric acid. A high-throughput technology has been developed for the study of potential catalysts in the oxidation of SO2to SO3. High-throughput methods are reviewed and the problems encountered with their adaptation to the corrosive conditions of SO2oxidation are described. We show that while emissivity-corrected infrared thermography (ecIRT) can be used for primary screening, it is prone to errors because of the large variations in the emissivity of the catalyst surface. UV-visible (UV-Vis) spectrometry was selected instead as a reliable analysis method of monitoring the SO2conversion. Installing plain sugar absorbents at reactor outlets proved valuable for the detection and quantitative removal of SO3from the product gas before the UV-Vis analysis. We also overview some elements used for prescreening and those remaining after the screening of the first catalyst generations.
