摘要

Procedure for the preparation of sulfuric acid and/or its salts and possibly SO2, using SO2 from the roasting of iron sulfides or from any other origin, characterized by the fact that the catalysis of the reaction of conversion of SO2 into SO3 it is entrusted to the oxide mixture that contains the optimal percentage of Fe2O3 from the roasting of said sulfides; said oxides being kept in suspension or in a fluid state by the same roasting gases and/or by the secondary air in the reactor on purpose.
