Effect of the gas phase composition on the vanadium catalyst properties used in sulfuric acid production
Four samples of com. V catalysts were taken from an industrial plant for manufg. H2SO4 (fresh and after 1-3 yr of operation) and analyzed for V2O2, K2O and Fe contents, for porosity and for activity in SO2 oxidn. at 380-620 degrees C. The presence of F compds. and moisture in the gas phase resulted in the catalyst deactivation.
