| 330 | _aVanadium(V) oxide catalysts for the selective oxidation of hydrogen sulfide to sulfur on a nonporous glassfiber support with a surface layer of a porous secondary support (SiO2) are studied. The catalystsare obtained by means of pulsed surface thermosynthesis. Such catalysts are shown to have high activity andacceptable selectivity in the industrially important region of temperatures below 200°C. A glassfiber catalystcontaining vanadium oxide (10.3 wt % of vanadium) in particular ensures the complete conversion of H2S ata temperature of 175°C and a reaction mixture hourly space velocity (RMHSV) of 1 cm3/(gcat s) with a sulfuryield of 67%; this is at least 1.35 times higher than for the traditional iron oxide catalyst. Using a structuredglassfiber woven support effectively minimizes diffusion resistance and greatly simplifies the scaleup of processes based on such catalysts. Such catalysts can be used for the cleansing of tail gases from Claus units andin other processes based on the selective oxidation of H2S. | ||
