Characterization by temperature programmed techniques of spent and acid treated vanadium catalysts

Show other versions (1)

Spent samples of V2O5/SiO2-γAl2O3 catalyst used for H2SO4 production were acid treated to recover vanadium. Fresh, spent, and acid treated samples were characterized by temperature-programmed techniques: TPR-H2, TPO-O2, TPD-NH3 and, TGA-DTA in order to determine the effect of deactivating species o...
