In situ visible microscopic study of molten (Cs2SO4V2O5)-V-.-soot system: Physical interaction, oxidation rate, and data evaluation
In situ visible microscopy has been used to characterise the physical interaction between soot and (Cs2SO4V2O5)-V-., a potentially attractive catalyst, under oxidation conditions. Upon heating to its melting point, (Cs2O4V2O5)-V-. shows both mobility and attachment to the soot particle. This creates a liquid catalyst-soot-gas interface that is favourable, for the oxidation reaction. Microscope image data can be used to estimate the oxidation rate, which is in good agreement with data obtained from TGA and fixed bed experiments. (c) 2005 Elsevier B.V. All rights reserved.
