method for activation of a catalyst from antimontetroxyd combined or mixed with zinndioxyd

摘要

Oxidation catalysts consisting of or containing SnO2 and Sb2O4 in combination or admixtures are activated by contacting the catalysts subsequent to calcination at 500-1100 DEG C. with boiling water or aqueous solutions of an acid or a base e.g. CH3COOH, HCl or NH4OH.
