TiO2 BASED SCRUBBING GRANULES, AND METHODS OF MAKING AND USING SUCH TiO2 BASED SCRUBBING GRANULES |
摘要 |
TiO2 based scrubbing granules, and methods of making and using such TiO2 based scrubbing granules are described. TiO2-based scrubbing granules include granulated TiO2 and about 0.5% to about 20% dry weight inorganic salt binder. Other TiO2 based scrubbing granules include unsintered granulated TiO2 and about 0.5% to about 20% dry weight inorganic salt binder. Inorganic salt binder include sodium aluminate. Methods of making TiO2 based scrubbing granules include i) combining TiO2 particles with inorganic salt binder to form TiO2-binder mixture comprising from about 0.5% to about 20% dry weight binder; ii) granulating the TiO2-binder mixture; and drying the granulated TiO2-binder mixture to form TiO2-based scrubbing granules. Methods of using such TiO2-based scrubbing granules include introducing TiO2-based scrubbing granules to remove adherent deposits on an inner surface of a reactor or heat exchanger during processes of forming TiO2 particles and finishing the formed TiO2 particles into finished pigment products. |
