Ammonium bisulfate → Sulfuric Acid

Reaktionsschritte

At the conclusion of the thermal decomposition reaction, solids or molten liquid comprising the decomposition product are removed from the reactor or allowed to cool in the reactor. In either case, water is added to the decomposition product to produce a second stream. With ammonium sulfate as the primary compound in the ammonium sulfate (first) stream, the addition of water converts preferably all or most of the ammonium pyrosulfate which may be present to ammonium bisulfate. With other sulfate salts present in the ammonium sulfate stream, the corresponding pyrosulfate salts, if present, are converted into bisulfate salts. Without wishing to be bound by theory, when water is added to the decomposition product, salts may be formed in equilibrium with ammonium sulfate and sulfuric acid.
