Decomposition of ammonium sulfate residue in a high solid/gas ratio suspension state with an industrial-scale reactor system (production line)

- Ammonium sulfate residue was decomposed in suspension state with a high solid/gas ratio.
- An industrial-scale reactor system (production line) was developed to produce active CaO via decomposition.
- Optimum operating conditions for the decomposition were determined.
- The product had a porous structure and a large specific surface ensuring high activity.
